Esztergomi Bazilika
This immense basilica, the largest in the country and visible from miles around, is the seat of the cardinal primate of Hungary. Completed in 1856 on the site of a medieval cathedral and recently restored, the basilica's most wondrous feature is the Bakócz Chapel (1506). Named for a primate of Hungary who only narrowly missed out on becoming pope, the chapel—on your left as you enter—is the most beautiful work of Renaissance architecture in all of Hungary; note its red marble, magnificent carvings, and enormous altar painting. Other highlights to look for are the sacristy, which contains a valuable collection of medieval ecclesiastical art; the vast and deep crypt, where the cathedral's builders and key priests are buried; and the treasury, containing a trove of precious ecclesiastical objects. For a great view of Esztergom, climb the long, winding staircase up to the observation platform in the cathedral's cupola, or take a stroll around the back of the building to the impressive Szent István megkoronázása (St. Stephen's Coronation) sculpture. Each section of the basilica's interior requires an entrance fee, from 500 HUF to 2,000 HUF, so your best bet is to purchase the combination ticket.
