The tallest building in Croatia, the Zagreb Cathedral is known for its two huge spires and massive nave, making it one of the most distinctive buildings in the capital. This Gothic construction, the most famous in the city, was built in the 11th century and is a center of tourist activity in the Upper Town which, depending on your preferences, may or may not be a good thing. Admission is free, however, so your list of reasons not to investigate this beautiful national landmark will be a short one. The cathedral is located at Kaptol 31 and, for those who are interested, is dedicated to Saint Stephen and Saint Ladislaus (along with the Virgin Mary, of course).
Note:This church is known as either the Zagreb Cathedral or Cathedral of the Assumption of the Virgin Mary.
