Gathered against and within St. Brigid's Cathedral in Kildare town is a quiet accumulation of stone that spans roughly seven centuries of ecclesiastical life. Cross slabs, grave slabs, decorated stones, three effigies, and a number of architectural fragments have been brought together here, dating from the 10th century through to the 17th. Individually, each piece is a fragment of something larger and now lost; collectively, they form an unusually concentrated record of how sacred space in this part of Leinster was built, marked, and mourned over a very long period.

Among the architectural fragments, a few pieces stand out for what they reveal about the buildings they once belonged to. Researchers Bradley et al., writing in 1986, documented a possible altar stone, a substantial slab of around 1.48 metres in length, incised with a plain Latin cross. There is also a sandstone centre window spandrel, the triangular space between the curves of a window arch, from what appears to have been a twin-light, cusped ogee-headed window, still grooved where glass was once set into it. A limestone window head with undecorated hollow spandrels survives too. Perhaps the most quietly remarkable object is a piscina, a liturgical basin used by a priest to rinse his hands and the sacred vessels during Mass, the drainage water being directed into consecrated ground rather than ordinary drains. This one is an almost square limestone block with a shallow circular bowl, only 20 centimetres across, its interior formed by radiating concave scallops that draw the eye down to a central drainage hole. It is a small, functional object, but the care taken in its shaping suggests it was made for a building of some standing.
