Opened in 1933, Trelai Park is a large open space in the Caerau area of Cardiff.

Formerly used locally as a race course, the area now provides sports pitches complete with large car park and changing rooms.

In the middle of the park is the site of a Roman Villa dating from the first century AD.


  • Roman Villa site: In 1894 a first century Roman villa was discovered on Ely Racecourse and excavations were carried out in 1922. The site of the villa is still visible as an un-mown area in the middle of Trelai Park, although the excavations have been covered over. The site is a scheduled ancient monument.
