The Baltimore Beacon is a conical white stone tower about 15 metres high, standing on the cliffs at the entrance to Baltimore harbour. Locals call it Lot's Wife, or the pillar of salt. It's a daymark for ships, not a lighthouse, and it never had a light. It was built in 1847–49 to replace an earlier, smaller beacon that had been badly built and vandalised.
Walk out from the village along Beacon Road; the clifftop views take in Sherkin Island, the harbour mouth and the open Atlantic.
