Liakopoulos, another revolution hero, originated from there, and his house can been visited in the village. In the house, there is a collection of Liakopoulosí personal items and historical relics. In the village square is the church of Agios Georgios (19th century). Near the village (Leniko) are parts of ancient fortifications. This is probably the citadel of ancient Melaines, an important ancient town of Iraia, which is also mentioned by Pausanias.
