The wooden church of St. John the Baptist was built in 1791. The church tower was built in 1818. The church was renovated in 1959. The church is based on the construction of a log house, with a tri-point closed-off chancel, built in the Baroque architectural style. The narrow-sided tower originates from 1818, whilst the ridge turret is covered with a gourd-like apex. The church contains a late-Baroque main altar with statues of two bishop saints and paintings of Saints Augustine of Hippo or Zechariah and one of St. John the Baptist.

The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
