Although the Farnes are famous for their non-human inhabitants, there have been some significant human inhabitants too and they've left their mark.
On Inner Farne, St Cuthbert's Chapel, built in the 14th century and heavily modified in the 19th, is open to the public. The other buildings, which are not open to the public but can be seen, include a medieval pele tower (which is home to the rangers) and a Georgian lighthouse. There is also a visitor centre with a small shop, and a toilet.
See the History page for more details on the buildings.
