Excavations have uncovered the foundations of a temple to Asklepios from the Hellenistic period (300-100 BC), which had a sacrificial altar. The temple stood in the centre of a courtyard surrounded by porticoes; the bases of the columns have been uncovered. Next to the sanctuary is a theatre; adjoining it are the council chamber and the Propylaia (monumental portal). To the west, the Temple of Artemis Orthia; to the north, the sebasteion; to the south of the Asklepieion were the public baths.

Pandánassa Monastery was founded in 1428. The beautiful church dedicated to the Queen of the Universe (Pandánassa) is a combination of two plans: a three-aisled basilica surmounted by a six-domed cruciform design. The belltower and the lower part of the apses date from the 14C, whereas the rest of the building is early 15C. The best paintings, which are lively and picturesque, date from the 15C.

On a spur of rock rise the crenellated walls and towers of the Castle of Port de Junch built in 1278 on the foundations of an ancient acropolis. The Frankish fortress, which consists of a circuit wall and a keep, commands the lagoon and the ancient port of Pylos. At the foot of the cliff there is a cave with stalactites, named after King Nestor, which is linked to the castle by an underground passage.

Within the walls of Vrondohíou Monastery are two great churches, St Theodore's and Odigítria, which have been heavily restored. St Theodore's was built on the cruciform plan in the late 13C. The dome, which rests on a sixteen-sided tall drum, is the most imposing feature both inside and outside. The Church of Odigítria, also known as the Afendikó, was built in the 14C by Pachomios, an important ecclesiastic in the Orthodox Church. The interior is decorated with remarkable 14C murals.
