The Rotunda of St. George in Skalice is built in the early Romanesque style, dating back to the first half of the 13th century. It was built as a church on a fortified settlement. The rotunda served as a church with a small burial area. Later it was rebuilt in the Gothic and Baroque styles. It is the oldest historical-architectural monument in the city.
The upper part, connected to the fortifications, served as a watchtower, the lower part continued to serve as a chapel. Fragments of wall paintings with motifs of the legend of St. George have been preserved in the interior from this period.
The central circular building is extended by a horseshoe-shaped apse, it has a Baroque dome with lanterns, its apse with a conch have remained in its original Romanesque form. On the outside of the apse there are traces of two Romanesque windows. The masonry consists of smaller sandstone blocks.
