Below the old town of Polignano a Mare in Puglia, Lama Monachile opens into a small pebble cove also known as Cala Porto. High rock walls enclose the shore, with pale town buildings along their upper edges. A pedestrian route leads down from the historic centre by the bridge.
The cove occupies the terminal reach of a coastal valley, held between high banks with a relatively level floor partly covered by alluvial deposits. Its shape records a long sequence of change: regional uplift and repeated Quaternary sea-level shifts altered the valley’s profile as it cut into the rock. Here the sea meets a landform shaped over far more time than the town’s familiar view suggests.
The rounded stones at the waterline tell a more immediate story. Coastal erosion supplies much of the beach sediment as waves wear back the cliff; the surf then reworks, smooths and rounds those fragments. The valley sides expose Cretaceous rocks of the Calcare di Bari formation. About 15 metres of limestone, calcarenite and fossil-rich beds are visible, including the Sannicandro guide level, a distinctive layer used to identify the rock sequence.
Lama Monachile is compact, popular and especially busy in summer. Its beach is reached on foot from the historic centre, but current route conditions, entry rules and facilities should be checked before setting out. Regional trains stop at Polignano a Mare on the Bari–Lecce route; consult live timetables and local access notices for your travel date.
