Teach Fiontaire or the House of St Fintan, is the site of a small church near Claggan graveyard. He was the author of the "Pagan History of Ireland" and is said to have lived to a very old age. At he nearby well, which is dedicated to him, a station was performed on three Saturdays before 15th August.

In Claggan there is a fine stately building known as the Rock House - surrounded by various trees / shrubbery imported and planted there by local landlords, especially Thomas Birch, who died in 1868, and by his successor Edward H. Clive.

The result of their endeavours was a modern farm using up-to-date machinery and giving considerable local employment. Silage which many consider a present - day method of farming, was harvested in Claggan many years ago.
