This rectangular fortification, measuring 8.7 metres in length and 6 metres in width, dates back to at least 1574, when historical records show it under the ownership of Shane Oge fitz John fitz Ed. Local historian Fahey noted in 1893 that the townland was previously known as Corbally, which aligns with the castle’s appearance in a 16th-century list as “Corbally castle”.

Today, only the ground floor and portions of the first floor survive of this once-imposing structure, which was later incorporated into the easternmost wing of an 18th-century country house; that grander residence now lies in ruins as well. The tower house retains several notable architectural features despite its condition, including a pointed arch doorway in the southeast wall with a defensive gun loop built into its eastern jamb, and part of a single-light window on the first floor of the same wall. The side walls display a slight base batter, a common defensive feature that helped deflect projectiles and strengthen the foundation.

The castle’s location appears to have been strategically chosen, with a church situated approximately 240 metres to the north, suggesting this was once a significant settlement in medieval Galway. The incorporation of the tower house into a later country house speaks to centuries of continuous occupation and adaptation, a common pattern in Irish castle architecture where medieval fortifications were transformed into more comfortable residences as the need for defence diminished.
