The old town of Zamość included on UNESCO World Cultural Heritage List was constructed between 1580-1591 in the style of late Italian Renaissance. The Great Square looks particularly impressive with its lavishly adorned coloured facades of the burgher houses. But the landmark of Zamość is its town hall with its broadly spread stairs which are often used to stage performances and concerts. In the house named Pod Aniołami, just off the square, the Regional Museum is situated today. The most important historical buildings are in the vicinity of the square. It is worthwhile seeing the massive fortifications, which successfully defended the city against the aggression of its enemies.
