Rotunda of St. George and St. Adalbert
The rotunda of St. George and St. Adalbert at the top of Říp Mountain is a Romanesque rotunda, one of the oldest preserved buildings in the Czech Republic. The first written mention of the rotunda dates from 1126, but the building was founded earlier, perhaps around 1039, when the remains of St. Adalbert were transferred to Prague. The present appearance of the rotunda is the result of a purist reconstruction which took place in 1869-1881.
