This 16C timber-framed house contains souvenirs and documents relating to Ernest Renan. Visitors can see the room where he was born, a reconstitution of his study, his library at the Collège de France and the two rooms where he liked to work as a child.

One of Brittany's finest cathedrals, dating principally from the 14 and 15C. Three towers stand on the transept. On the south side is an attractive «bell portico», surmounted by a flamboyant window. The Romanesque Hastings Tower dates from the 12C. The interior of the church is exceptional. It has 46 Renaissance stalls and 15C sculpted funeral recesses representing knights in armour. The treasury and cloister are also worth a look.

Stretching from Porz Rolland to Porz ar Mor, this rocky coastline is one of Brittany's finest natural sites, with rocks of all shapes and sizes along the shore facing the Sept Îles archipelago. The most interesting area is the Pointe de Squéouel, a headland of gigantic rocks. Visitors to the area will also discover strange formations such as the “Turtle”, “Rabbit” etc.

On the beach is an oratory to St Guirec who landed here in the 6C. A granite statue of the saint has replaced the primitive wooden effigy which suffered from a rather disrespectful custom: young ladies wishing to marry used to stick a hairpin in the saint's nose. The beach is sheltered by rosy-hued rocks of exceptional beauty.

This pile of rocks commands a view which stretches along the coast, taking in the islands of Milliau, Molène, Grande and Losquet.

From the viewing table, there is a fine view of the coast from Ile de Batz and Roscoff right over to Ile Grande and Triagoz Lighthouse out at sea.
