The 15th-century parish church, dedicated to Saint Stephen, is in Perpendicular Gothic style, and is noted for its early organ and organ case, early stained glass, fine rood screen and large pre-Norman font. Adjacent to it are earthworks known as Old Radnor Castle, but it is unclear if this was ever in fact a fortification.[2]
Riddings Brook, a tributary of the River Lugg, starts near Old Radnor. Old Radnor has one pub, the Harp Inn, a 15th-century farm house.
New Radnor, which had replaced Old Radnor as the county town of Radnorshire, is further to the west.
In 2018 a Review of Electoral Arrangements proposed that Old Radnor and Gladestry be included with nearby Painscastle under a new ward with the name Glasbury and Old Radnor. If accepted, the proposed change would take effect from the 2022 election.[4]
At the local level, Old Radnor Community Council represents the community. It comprises up to eleven community councillors representing the community wards of Old Radnor/Walton and Kinnerton/Evenjobb.[5]
