St. Lawrence Church on the Petrin Hill in Prague.
The original Romanesque and Gothic church was rebuilt in 1784 and converted into a residential house with small apartments. It wasn't until 1985 that the crumbling building underwent a six-year renovation. The church was converted into a concert hall while preserving its original architectural qualities to the maximum extent possible. It is mainly used for concerts of Prague Spring.
