Morlaix Bay, a constellation of islands and islets, is a vast gulf around 100 kilometres wide in north Finistère. It is a delight for sailors who enjoy sailing through these natural and authentic landscapes, where the reliefs, endlessly redrawn by the tides, guarantee a truly unusual setting. Discovering château du Taureau from the sea is a memorable experience. This 16th century fort built on a rock to protect Morlaix from thieves and then from the English, was used by Vauban to design the current rectangular fortress. This former garrison became a prison then a bourgeois summer residence and has been a listed historical monument since 1914.
