Once an important harbour of Peljesac,
Trpanj developed near a Roman villa (fragments of mosaics and walls on the
old graveyard). Ruins of a mediaeval fortress rise on the hill above the
port. The church of Our Lady of Karmen (Renaissance main altar with
the coat of arms of the Gundulic family) is in the centre of the town. The
new parish church was built in neo-Romanesque style; a 16-th century
ornamented stone window of an older church has been preserved. A small
chapel (inscription from 1695) with a wooden Baroque altar is on the edge of
the village.
Beautiful beaches surrounded by groves of pine, numerous inlets, lavish Mediterranean vegetation and fresh water springs are distinctive features of Trpanj. Various accommodation opportunities (hotels, boarding houses, apartments), domestic food (fish and wine), sports and recreation facilities and intact nature of the island's interior famous for its quality wines attracts many regular guests. Trpanj is also known for medicinal mud.
