Beginning in 1653, the St-Gervais-et-St-Protais church employed and sheltered the Couperin family, one of the most famous dynasties of French musicians, for more than two centuries. On one side of the church, the home of the famous harpsichordists, organists, and composers still stands, with a plaque commemorating the Couperins' tenure in this place. The organ used by Louis and François Couperin still exists today inside the church. Built by the most famous organ builders of the time — François-Henri Clicquot, Louis-Alexandre Clicquot, and Robert Clicquot — it is a fine example of the French baroque style.
This church site is one of the oldest in Paris. Its existence at this place is mentioned as early as the fourth century. Dedicated to Gervasius and Protasius, the church was formerly the seat of the powerful brotherhood of wine merchants. It assumed its present appearance in the 16th century. Its façade was completed much later, however, about 1620.
The present church was begun in the Gothic style in 1494, the chapels of the apse were finished in 1530 and the transept in 1578. The doorway of the church was built in 1616–1620 by Claude Monnard in the classical style. Between 1600 and 1628, a second row of chapels was built on the north side including the golden chapel ornamented with painted woodwork.
The church was refurbished to coincide with Pope John Paul II's second visit to Paris with the continued installation of a number of new stained glass windows (Claude Courageux, earlier work by Sylvie Gaudin.
One side of the church is skirted by the Rue François Miron, where two of the oldest medieval houses of Paris survive, at numbers 11 and 13. They date, most likely, from the 14th century. One can see the exposed wood of the half-timbered structures.
On 29 March 1918, a German shell, fired by the long-range 'Paris Gun', fell on the church, killing 88 people and wounding 68 others; the explosion collapsed the roof when a Good Friday service was in progress. This was the worst single incident involving a loss of civilian lives during the German bombardment of Paris in 1918. Among those killed was Rose-Marie Ormond Andre-Michel, the niece and a favorite model of John Singer Sargent.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
