St. Bartholomew's church

St. Bartholomew's Church in Šiška is a national monument featuring preserved Romanesque architectural elements, particularly the northern portal. The structure was redesigned in the 1930s by architect Jože Plečnik, who integrated modern elements while respecting the building's medieval core.

The church gained prominence in 1370 when Habsburg rulers and Venetian representatives signed a significant treaty here. Its origins trace back earlier, and it later underwent major changes that reflected the shifting religious landscape of Ljubljana.

The church served as a place where different faiths came together throughout Ljubljana's history. It accommodated Protestant worship and later Catholic services, making it a physical record of the city's changing religious life.

The church is easily accessible and operates as an active place of worship with regular services. Visitors will have the best experience exploring the building and its architectural features outside of service hours.

A circular opening in the roof above the main entrance was deliberately designed by Plečnik to allow a lime tree to grow through the church structure. This unusual feature merges nature with the building in an unexpected and memorable way.
