In 1862 a lighthouse was built on the reef. Nowadays it shows a light to the ships that it formerly led astray; what used to be a trap now bears a torch. Seamen scan the horizon for this rock, now a protector and a guide, which they formerly shunned as an evildoer. It now reassures the vast nocturnal expanses in which it formerly inspired fear. It is rather like a robber turned gendarme.
