The main settlement and communal seat is situated on the north side of a harbour called Barachois, which faces the Atlantic Ocean, on the Saint-Pierre Island's east coast.

[5] Close to the centre of the harbour's edge lie the Post office and Custom House (staffed by Directorate-General of Customs and Indirect Taxes), behind which is General Charles de Gaulle Square, the town's centre.

Other prominent landmarks include the St. Pierre Cathedral, to the north of the square, rebuilt from 1905 to 1907 after a major fire, and the Pointe aux Canons Lighthouse, at the mouth of the harbour.

Further north, close to the town's former hospital, is the Fronton Zazpiak Bat - an arena for the traditional Basque sport of pelota.

There is an attached senior home offering health services at the Maison de retraite Eglantine.

[13] Public primary schools in the commune:[14] Lycée-Collège d'État Émile Letournel is the public secondary school in the commune, with junior high, vocational high, and general senior high/sixth-form programmes.
