An unobtrusive door on noisy Karmelitská hides the entranceway to a fascinating sanctuary that also has one of the best views over the Lesser Quarter. The street door opens onto the intimate courtyard of the Vrtbovský palác (Vrtba Palace), which is now private housing. Two Renaissance wings flank the courtyard; the left one was built in 1575, the right one in 1591. The original owner of the latter house was one of the 27 Bohemian nobles executed by the Hapsburgs in 1621. The house was given as confiscated property to Count Sezima of Vrtba, who bought the neighboring property and turned the buildings into a late-Renaissance palace. The Vrtba Garden was created a century later. This is the most elegant of the Lesser Quarter's public gardens, built in five levels rising behind the courtyard in a wave of statuary-bedecked staircases and formal terraces reaching toward a seashell-decorated pavilion at the top. In summer it's a popular spot for weddings, receptions, and occasional concerts. (The fenced-off garden immediately behind and above belongs to the U.S. Embassy -- hence the U.S. flag that often flies there.) The powerful stone figure of Atlas that caps the entranceway in the courtyard and most of the other classically derived statues are from the workshop of Mathias Braun, perhaps the best of the Czech baroque sculptors.
