The remains of this monastery are found on the grounds of an equestrian centre approximately 1.5 km from today's Saggart Village.

By 1207, Saggart, or Tasagart, as it was then called by the Normans, had been made a prebend of St Patrick's Cathedral, Dublin.

Several objects of archaeological interest are located in Saggart, including a pair of megalithic standing stones in Boherboy, that are known locally as Adam and Eve.

It is home to the Citywest Hotel, which hosts many annual events including the Irish Masters, award ceremonies, and political ard fheiseanna.

[8] A new walking trail incorporating the Slade Valley is expected to be completed in the coming years.

The section of the trail adjacent to Saggart Reservoir is currently under construction and runs alongside the boundary of the site.

[9] The development of the Slade Valley trail was marked as one of the Key Actions under the South Dublin County Council Tourism Strategy 2015-2020 where it is intended to take in Rathcoole, Saggart and Brittas with looped access to villages and other attractions.

For elections to South Dublin County Council, Saggart is part of the local electoral area of Clondalkin, along with Citywest, Rathcoole and Newcastle.
