Over a causeway leading away from the town with lovely lakes on either side lies the beautiful Radziwill Palace Fortress (1583), the main sight in Nyasvizh. In Soviet times it was turned into a sanatorium but it has been fully restored in recent years and is looking superb.
With over 30 fully refurbished state rooms now open, a very impressive inner courtyard and clearly labelled displays, you can easily spend a couple of hours looking around. The hunting trophies rooms is well worth the price of entry alone. There are lovely gardens to explore as well, although at weekends the place can be overrun with tour groups.
The gardens are full of street food vendors, so you can easily gather supplies for a picnic in the lovely grounds.
