This town on the banks of the Danube is the seat of the Roman Catholic Primate of Hungary, the Archbishop of Esztergom. St Stephen (1000-1038) the first Hungarian king, the founder of the country, was born in the castle built here in 972. The Cathedral (Szent István Square), the largest church in the country, is the emblem of the town and dominates Castle Hill. Rebuilt in the 19th century in Classical style, it houses the largest altar-piece in the world, painted on a single piece of canvas. Of unique interest is the only intact Hungarian Renaissance building, the Bakócz Chapel. Built of red marble at the beginning of the 16th century, it is 300 years older than the church itself.
