Keeper test: how many flashes are in one group?

Watch the light, count the flashes, then answer to earn a keeper star.

The signal runs in real time and is simplified for the screen.

Fanad Head Lighthouse on its green headland
The lighthouse and keepers’ houses sit on a headland above the cliffs.

At the northern tip of the Fanad Peninsula in County Donegal, a white tower stands on a green headland between two long sea inlets, Lough Swilly and Mulroy Bay. Fanad Head Lighthouse is often counted among the most beautiful lighthouses in the world.

Born from a shipwreck

Lough Swilly gave ships shelter from Atlantic storms, but its entrance was dangerous in the dark. After the frigate HMS Saldanha was wrecked here with the loss of all on board, a lighthouse was planned, and the first light was shown in 1817. The present, taller tower was built in 1886.

Two colours of light

The light gives five flashes every 20 seconds. Seen from most of the open sea it is white, but in some directions it shows red, warning ships away from rocks and shallows. Sailors can tell from the colour whether they are on a safe course. The station was automated in 1983, and the light still works today.

At dusk the light begins its five-flash signal.

Stay with the keepers

When the keepers left, their stone houses were restored. Today visitors can take a tour of the tower and even stay overnight in the old keepers’ houses, with the sound of the sea all around.

Visiting tips

  • The road to the headland is narrow and winding, so allow extra time.
  • On clear nights the headland is a good place to watch the stars, and sometimes the northern lights.
  • Check opening times for tower tours before you go.
