The Zagreb Cathedral on Kaptol is a Roman Catholic institution and not only the tallest building in Croatia, but also the most monumental sacral building in Gothic style southeast of the Alps. It is dedicated to the Assumption of Mary and to kings Saint Stephen and Saint Ladislaus. The cathedral is typically Gothic, as is its sacristy, which is of great architectural value. Its prominent spires are considered to be landmarks as they are visible from most parts of the city.
