The conference building is located in the historical quarter of Prague called Lesser Town in a walking distance from the Prague Castle , Old Town and Charles bridge. The baroque building (so called House for Professed) was built in the 17th century by the Society of Jesus (SJ) as the seat of the most important representatives of the Order. The plans of the building elaborated by Italian architects are now preserved in the National Library in Paris.


The conference venue at Malostranske namesti

During reconstruction of the building in 2004 foundations of Romanesque St Wenceslas rotuda were discovered. They were renovated and on September 28, 2016 the St Wenceslas rotunda was reopened after almost 400 years. See virtual tour through the Rotunda basement. A lion tile from the Rotunda medieval floor is used in the SLOPOS-15 logo.


The building adjoins a gem of Prague baroque, St. Nicholas Church , built in the period 1704-1755. The Church of St Nicholas, the most famous Baroque church in Prague, stands along with the former Jesuit college in the centre of the Lesser Town Square. A Gothic parish church consecrated by Prague Bishop Tobias in 1283 stood at the site until 1743; nearby was the Romanesque Rotunda of St Wenceslas, which had been built in memory of the miracle that occurred during the transfer of Wenceslas' body from Stara Boleslav to the Prague Castle, as mentioned in medieval legends. Today's Church of St Nicholas is one of the most valuable Baroque buildings north of the Alps. Construction lasted approximately one hundred years, and three generations of great Baroque architects - father, son and son-in-law - worked on the church: Krystof Dientzenhofer, Kilian Ignac Dientzenhofer and Anselmo Lurago.

The Jesuit Thomas Schwarz built the small and main organs as well as many others in Bohemia. Built in 1745-47, the main organ has over 4,000 pipes up to six meters in length. W. A. Mozart played this organ during his stay in Prague as a guest of the Duseks. The Church of St Nicholas is a superb example of High Baroque architecture, a building that astonishes visitors with its size and monumental interior. As the most prominent and distinctive landmark in the Lesser Town, no panoramic view of the city would be complete without its silhouette below the Prague Castle.
