It was a deliberate act with obvious military logic: a lighthouse is a gift to whoever holds the sea next, and this one had marked the mouth of the Gulf of Finland since before there was an Estonia to argue about. The stone tower that came down that day was itself a replacement, built in 1850. The one that stands now went up in 1954 - a 35-metre column of reinforced concrete in bold black and white bands, its light 39 metres above the sea. Counting back through the collapses, the demolitions and the improvised wooden stopgaps, Osmussaar is on at least its fifth beacon in two and a half centuries. The island keeps losing its light and keeps rebuilding it, because the alternative is unthinkable to anyone who has to sail past.

In 1804 it was raised and fitted with a proper lantern room, its light produced by a catoptric apparatus - twenty-four oil lamps, each sitting in front of a polished reflector that gathered the flame's scattered glow and threw it seaward. T...

In June 1940 the Soviet Union cleared Osmussaar of its inhabitants - about 130 people, overwhelmingly Estonian Swedes whose families had farmed and fished here for some seven centuries - and turned the island into a coastal ...

Reinforced concrete, 35 metres tall, focal plane at 39 metres, painted in the broad horiz...
