Renvyle Castle was a three storey tower house, believed to have been built in the late 13th/early 14th century by the Joyce family, but it has been disputed that the origins of the castle trace to the O’Flaherty family.
Legend has it that there was a wedding taking place of one of the Joyce’s at the castle, when it was interrupted by the O’Flaherty’s, a rival family, and all guests, except one, were massacred. The O’Flaherty’s are believed to have took over the castle thereafter.
It is understood that Donal O’Flaherty and Grace O’Malley (Granuaile Ni Mhaille) lived in the castle (around 1546), until Donal was eventually murdered and Grace gave up the castle in order to seek revenge. It was recorded that the castle was later occupied by Miles MacTibbot in 1574.
Although the castle is now in ruins, some architectural features can still be seen.
