Fallmore is a town-land near Belmullet with Blacksod Bay to the south and east, and the rolling Atlantic to the west.

It is an area of large scale granite boulders and, on a hilltop overlooking Blacksod Pier, there is the last sculpture of the North Mayo Sculpture Trail: Deirble's Twist. This sculpture is based on the local legend associated with St Dervilla. It's made by raising the existing granite boulders on site and placing them in an ascending spiral.

At Fallmore there are also the surviving ruins of Deirble’s Church built in 12th century and Saint Deirble’s well. According to legend, the waters from the well can cure eye complaints.
