Located at the end of the Belmullet Peninsula the Glosh Signal Station is a rare example of a site easily viewed from the side of the road. The site has restricted views to the east but clear views in all other directions although neither of the ruined stations on Achill Island to the south or Tower Hill to the north can now be seen. The signal station consists of a well preserved signal tower set within a large rectangular enclosure that has been reduced almost to the height of the surrounding fields. A small lime kiln is located to the west of the signal tower. The signal tower is the best preserved example in County Mayo.

The signal tower survives close to its full height although the machicolation that would have protected the first floor doorway on the western wall has fallen. The tower measures 6.1m across and has fine curved bartizans on the north east and south east corners and an unusually complete chimney a top the eastern wall. All of the dressed stonework from the window surrounds and the coping stones on top of the wall have been removed from the site.

The collapse of the machicolation and the wall over the doorway are potential problems for this site as the structure seems to be cracking in this area and without remedial work the site could suffer from a more substantial episode of collapse at any point.

Inside the tower the arrangement of features largely accords to the standard design but there are no traces of the presence of a split mezzanine level between the ground floor and first floor. The semi-basement is of note given the lack of infilling that has occurred meaning it may be close to its original depth at 1.3m.

The enclosure is barely visible at ground level but measures around 55m by 30m. The remains of the suspected lime kiln are little more than an oval depression 6.5m west of the signal tower that measures about 2.5m across.
