The Coastguard Station is about a 15 minute walk from Moville's Market Square. The only info I found on the station was from the Coastguards of Yesterday website which is below.
In April 1901 Father got promoted and we moved to
Coastguard Station Moville on the north shore of Lough Foyle in the
Innishowen peninsula. The Coastguard Station Moville contained 14 families in two blocks of seven cottages. Today they are holiday homes.
