Taghmon Church, Fortified church in Crookedwood, Ireland.

Taghmon Church is a fortified church in Crookedwood with a distinctive four-story tower and barrel-vaulted roof. The outer walls feature reinforced bases that extend along the perimeter, showing the sturdy construction typical of these medieval defensive structures.

A monastery stood here from the 6th or 7th century, founded by Fintán, also called Munna or Munnu. St. Munna's was built as a fortified church in the early 15th century and was plundered by Farrell Mageoghegan in 1452. After the Reformation it passed to the Nugent family and was almost ruined by 1622; the Church of Ireland used it again by 1755 and it was restored extensively in 1843.

The walls display carved ecclesiastical heads and a Sheela-na-gig figure above a north-facing window. These stone carvings show the craftsmanship that went into decorating medieval Irish churches.

The site sits in a rural location and requires a car to reach from Mullingar. Head on the N4 to junction 17, then follow R394 and turn onto L1618 to find it.

The tower's second floor was a living area with a fireplace, window seats and a slop stone — a channel through the wall for waste water. Above it lay a bedroom and garderobe, showing the tower housed the clergy as well as defending them.
