Waldegg Castle, or Schloss Waldegg, is a castle near Solothurn, in the municipality of Feldbrunnen-St. Niklaus of the Canton of Solothurn in Switzerland. It is a Swiss heritage site of national significance.

History The Baroque castle was built between 1682 and 1686 as a summer house for the Schultheiss Johann Viktor P. Joseph von Besenval (1638–1713) and his wife Maria Margaritha, née von Sury (1649–1713). Over time, the Waldegg Castle, together with the Palais Besenval, developed into one of the main residences of the family von Besenval.

House of Besenval: The rise of a family

The family Besenval was originally from Torgnon in the Aosta Valley. They had risen socially in the service of King Louis XIV and had received a title of baron (Reichsfreiherr) of the Holy Roman Empire from Emperor Leopold I in 1695. Furthermore, already in February 1655, Martin von Besenval (1600–1660), Johann Viktor P. Joseph's father, was ennobled by King Louis XIV and raised to knighthood in 1658 in gratitude for his merit for the French Crown. And on 11 August 1726, King Louis XV elevated the von Besenval family's possession of Brunstatt in the Alsace to a French barony. The culmination of the family's ennoblement was the elevation of Martin Louis de Besenval (1780–1853) to the rank of comte by King Charles X on 18 March 1830. The letters of nobility extended to his descendants. Some members of the family also adopted the French spelling of the name, de Besenval.Andreas Fankhauser: Besenval von Brunstatt, Historisches Lexikon der Schweiz (HLS), Version vom 23.06.2004, online, 2024Gabrielle Claerr Stamm: De Soleure à Paris : La saga de la famille de Besenval, seigneurs de Brunstatt, Riedisheim et Didenheim, Société d'Histoire du Sundgau, 2015, p. 44Gabrielle Claerr Stamm: De Soleure à Paris : La saga de la famille de Besenval, seigneurs de Brunstatt, Riedisheim et Didenheim, Société d'Histoire du Sundgau, 2015, p. 49Gabrielle Claerr Stamm: De Soleure à Paris : La saga de la famille de Besenval, seigneurs de Brunstatt, Riedisheim et Didenheim, Société d'Histoire du Sundgau, 2015, pp. 102–103Gabrielle Claerr Stamm: De Soleure à Paris : La saga de la famille de Besenval, seigneurs de Brunstatt, Riedisheim et Didenheim, Société d'Histoire du Sundgau, 2015, p. 187

However, the Besenvals' loyalty to the French Crown was also rewarded financially, as reflected in a remark by the French ambassador in Solothurn in 1709 that later became legendary:

The French money was a welcome financial boost for the construction of the Waldegg Castle.

The Besenvals became rich through the salt trade and the mercenary business with France. A mechanism that was common among mercenary patricians soon set in: Because the Besenvals had influence in their own town, they became important for foreign powers – and because they were valued abroad, their power in turn grew in their own town.

Johann Viktor von Besenval

Johann Viktor P. Joseph's son Johann Viktor, Baron von Besenval von Brunstatt, was a diplomat and colonel in the regiment of the Swiss Guards of France. After he inherited the Waldegg Castle in 1713, he had it renovated. Furthermore, he added a theater, commissioned in 1722 and completed in 1736, and a chapel, the Chapel of Saint Michael, commissioned in 1729 and decorated in the current French style, to the castle. He brought numerous works of art back with him from France.Christian Renfer / Eduard Widmer: Schlösser und Landsitze der Schweiz, Ex Libris Verlag AG, Zürich, 1985, pp. 156–157Gabrielle Claerr Stamm: De Soleure à Paris : La saga de la famille de Besenval, seigneurs de Brunstatt, Riedisheim et Didenheim, Société d'Histoire du Sundgau, 2015, pp. 104–105

Palais Besenval Johann Viktor von Besenval and his brother Peter Joseph (1675–1736) commissioned the construction of the Palais Besenval in Solothurn in 1703.Stefan Blank: «Der allhiesigen Statt eine Zierd» – Zur Geschichte und Bedeutung des Palais Besenval in Solothurn.

A wedding warmly welcomed by the French Crown

On 18 September 1716, Johann Viktor married Katarzyna Bielińska (1684–1761), daughter of Kazimierz Ludwik Bieliński, a Polish noble, politician and diplomat. She was also the sister of Maria Magdalena Bielińska, div. Gräfin von Dönhoff, who was the Maîtresse-en-titre of King Augustus II the Strong. A marriage warmly welcomed by Philippe II de Bourbon, Duc d'Orléans, Régent de France between 1715 and 1723, given that Johann Viktor von Besenval was serving as French ambassador to Poland at the time.Gabrielle Claerr Stamm: De Soleure à Paris : La saga de la famille de Besenval, seigneurs de Brunstatt, Riedisheim et Didenheim, Marriage de Jean Victor de Besenval et Katarzyna Bielińska et informations sur Kazimierz Ludwik Bieliński, Société d'Histoire du Sundgau, 2015, p. 98Genealogisch-historische Nachrichten von den allerneusten Begebenheiten, welche sich an den europäischen Höfen zutragen, Bogislaus Ernestus, Graf von Dönhoff.

Death in Paris and a funerary monument by Jacques Caffieri Johann Viktor von Besenval died on 11 March 1736 in his hôtel particulier on the Rue de Varenne in Paris. His funeral took place in the church of Saint-Sulpice, where he was also buried. His funerary monument in the church featured a bust relief made by Jacques Caffieri in 1737. During the French Revolution, his monument, along with those of other representatives of the Ancien Régime, was destroyed. However, an engraving of the monument survives in the Rijksmuseum in Amsterdam.Gabrielle Claerr Stamm: De Soleure à Paris : La saga de la famille de Besenval, seigneurs de Brunstatt, Riedisheim et Didenheim, Société d'Histoire du Sundgau, 2015, pp. 109–110

Peter Viktor von Besenval and his heirs

Johann Viktor's son Peter Viktor, Baron von Besenval von Brunstatt, a Swiss military officer in French service, was born at the Waldegg Castle in 1721. When his father died in 1736, he inherited the Waldegg Castle. However, he lived most of his life in France, where he was known as Pierre Victor, Baron de Besenval de Brunstatt, and where, in 1767, he bought the Hôtel Chanac de Pompaodur and made it his residence in Paris. Today the hôtel particulier is known as Hôtel de Besenval. It has housed the Embassy of the Swiss Confederation and the residence of the Swiss ambassador to France since 1938.Jean-Jacques Fiechter / Benno Schubiger: L'Ambassade de Suisse à Paris, Ambassade de Suisse, 2ème édition, août 1994, p. 11

Peter Viktor rarely stayed in Switzerland anymore. The center of his life was in Paris. Due to his absence, he left the use of the Waldegg Castle to his cousin Johann Viktor Peter Joseph von Besenval (1742–1786) and his wife Maria Anna Margrit, née von Roll (1741–1814). Although he wasn't often in Switzerland, Peter Viktor did add an orangery, the Pomeranzen-Hause, to the castle in 1780.Gabrielle Claerr Stamm: De Soleure à Paris : La saga de la famille de Besenval, seigneurs de Brunstatt, Riedisheim et Didenheim, Société d'Histoire du Sundgau, 2015, p. 144

The French Revolution: The beginning of the end of an era The French Revolution of 1789 was disastrous to the family's influence, business interests and wealth. Although all the family members survived the terror of the French Revolution, their close ties to the French royal family and other high-ranking members of the Ancien Régime made life more and more difficult for them in France.

Peter Viktor von Besenval, who was part of the highest circle of power in France, saw the dark clouds looming over the Ancien Régime in the course of 1789. After the Storming of the Bastille on 14 July 1789, he wanted to escape to Switzerland, to his country estate, the Waldegg Castle, but he was no longer able to do so. On 26 July 1789, he was recognised in Villegruis while fleeing revolutionary troops. He was immediately arrested and sent to prison. In October 1789 he was charged with the crime of lèse-nation. The baron was never to see the Waldegg Castle again. Only with good luck and good friends did he survive the terror of the revolution. He was acquitted on 1 March 1790. Peter Viktor von Besenval died on 2 June 1791 at his residence in Paris, the Hôtel de Besenval.Gabrielle Claerr Stamm: De Soleure à Paris : La saga de la famille de Besenval, seigneurs de Brunstatt, Riedisheim et Didenheim, Société d'Histoire du Sundgau, 2015, p. 150

Death in Paris without a legitimate heir

After the death of Peter Viktor von Besenval in 1791, who was in fact not childless but had no legitimate heir, the Waldegg Castle, which was a Fidéicommis and could therefore only be passed on in the immediate family, went to the firstborn son of his cousin Johann Viktor Peter Joseph, the minor Ours Joseph Augustin von Besenval (1777–1831).Gabrielle Claerr Stamm: De Soleure à Paris : La saga de la famille de Besenval, seigneurs de Brunstatt, Riedisheim et Didenheim, Société d'Histoire du Sundgau, 2015, p. 152

It would later fall to Ours Joseph Augustin von Besenval to handle the increasingly precarious financial circumstances of the family von Besenval after the French Revolution, which led to the loss of their once considerable French income. Years later, on 18 October 1830, the precarious financial situation led to Ours Joseph von Besenval marrying his only daughter and universal heir Marie Louise Emélie (1804–1838) to her first cousin Amédée de Besenval (1809–1899). Amédée was the eldest son of Ours Joseph von Besenval's brother Martin Louis de Besenval, first Comte de Besenval (1780–1853), and Anne Caroline, née von Roll (1786–1829).Gabrielle Claerr Stamm: De Soleure à Paris : La saga de la famille de Besenval, seigneurs de Brunstatt, Riedisheim et Didenheim, Société d'Histoire du Sundgau, 2015, p. 186

In order to avoid dispersal of the family heritage, marriages between cousins often occurred within the family von Besenval, but these led to a weakening of the line of descent due to excessive consanguinity. The result was increasing signs of degeneration.Gabrielle Claerr Stamm: De Soleure à Paris : La saga de la famille de Besenval, seigneurs de Brunstatt, Riedisheim et Didenheim, Société d'Histoire du Sundgau, 2015, p. 199

The biological child and heir of the Hôtel de Besenval Peter Viktor von Besenval's only child was his biological son Joseph-Alexandre Pierre, Vicomte de Ségur. After the death of his father in 1791, he inherited the bare ownership of the Hôtel de Besenval in Paris.Gouverneur Morris: Journal de Gouverneur Morris, par E.

The sale of the baron's furniture to the Swiss Confederation

On 19 May 1938, the Swiss Confederation purchased the Hôtel de Besenval in Paris as the country's new legation building. In the same year, the Swiss Government bought from the patrician family von Sury, the then owners of the Waldegg Castle, a sofa and six chairs, covered in beige fabric and embroidered with scenes from the fables of Jean de La Fontaine, except for the sofa, which is covered with a pattern of flowers and birds.
