St. George's Basilica
St. George's Basilica (Bazilika sv. Jiří) is the oldest surviving church building within Prague Castle and the best-preserved Romanesque church in Prague, founded around 920 AD by Prince Vratislav I — the father of St. Wenceslas. Its striking rust-red façade is Baroque, added in the late 17th century, but the interior is strikingly austere and Romanesque: plain limestone walls, simple columns, and a three-nave layout restored after a devastating fire in 1142. The basilica served as the burial church of the Přemyslid dynasty until 1055, and the tombs of Prince Vratislav and several other early Bohemian rulers remain in the nave. Its two distinctive white marl towers — the taller Adam to the south and the slightly tilted, narrower Eve to the north — are among the most recognisable silhouettes on the Prague Castle skyline. The adjacent St. George's Convent, founded in 973, is the oldest convent in Bohemia.
