The winding streets of the town, with its church towers create a historical atmosphere. Below the Basilica, at the edge of the mountain stand the old walls, bastions and rondellas – the remains of the castle of Esztergom. Still Prince Géza made Esztergom a royal seat in the 10th century. His son, (Saint) Stephen I. was born, crowned, and founded the first Hungarian archdiocese here, which continues to be the centre of the Hungarian Catholic Church. It remained a royal seat until the Mongol invasion, with its learned archbishops making it one of the Hungarian centres of humanism and religious renaissance.The frescoes of the palace date from the 12th-14th centuries, while on the walls of the mottes, some of the most beautiful paintings of the early Hungarian Renaissance can be admired (15th century). The castle successfully withstood a siege during the Mongol invasion, only the city was raided. In the 14th and 15th centuries Esztergom saw events of great importance and became one of the most influential acropolis of Hungarian culture alongside with Buda. The flourishing of Esztergom started around the time of the Anjou kings of Hungary, the opulent archbishopric made significant buildings on the castle hill. The summit of this golden age was at the time of Archbishop János Vitéz, a man of delicate renaissance education, when the dining palace was built on the side facing the river, and when the hanging gardens of European fame were created – their remains can still be seen on the side of the castle hill.
