This cromlech (circle of monoliths) overlooks Newport Bay. The capstone is perfectly balanced on top of other supporting stones. It was probably an important place of transit at the time of the megaliths.

Landward is a good stretch of the town walls, enclosing a characteristically intricate web of medieval streets, widening out at St Mary's, one of Wales' largest parish churches, with a 46 m-high spire. The Tudor Merchant's House, virtually unchanged, has Flemish fireplaces and period furniture.

The Harbourmaster's overlooks the harbour and was the first building on the new quayside. It adjoins the Aber Sea Aquarium, where a local fisherman and a naturalist present marine fauna, lobsters in particular, as well as the seals, dolphins and birds of Cardigan Bay.

This hilltop fort is the setting for an ambitious attempt to recreate the environment of the Iron Age: storage pit, cultivated areas and a trio of conical thatched huts with smoky interiors.
