The Church of the Assumption of the Virgin Mary lies next to the Blatná castle, at the end of the main square. It was founded in the 1290s as a two-aisled building with a long presbytery, and small adytum on the north side. It gained its present looks in 1515 when the reconstruction was finished.
The bell tower is located next to the church. It was first built in 1722–1723. It was destroyed with most of the town in the big fire of 1834, but was built again in 1835–1836, this time at 52 metres (171 ft) of height.
The Beckov castle stands on a steep 50 m tall rock in the village Beckov. The dominance of the rock and impression of invincibility it gaves, challenged our ancestors to make use of these assets. The result is a remarkable harmony between the natural setting and architecture.
The castle first mentioned in 1200 was originally owned by the King and later, at the end of the 13th century it fell in hands of Matúš Èák. Its owners alternated - at the end of the 14th century the family of Stibor of Stiborice bought it.
The next owners, the Bánffys who adapted the Gothic castle to the Renaissance residence, improved its fortifications preventing the Turks from conquering it at the end of the 16th century. When Bánffys died out, the castle was owned by several noble families. It fell in decay after fire in 1729.
The history of the castle is the subject of different legends.
