Cadw dates the church to the 14th century, although it stands on the site of an earlier priory.[1] The church was restored between 1878 and 1879 by Habershon and Fawckner and renovated in 1902–03 by Charles Busteed Fowler. Since the very early 19th century a chapel within the church had been used as mausoleum by the Morgan family, prominent local landowners whose Tredegar House estate lies just to the south.[a] This chapel was rebuilt in 1916 by W. D. Caröe for Courtenay Morgan, 1st Viscount Tredegar.[b][c][1]
St Basil's is an active parish church within the Tredegar Park Ministry Area which covers an area at the west of the city of Newport.[7] It hosts a thriving community choir.[8] A church hall was constructed in the early 21st century.[9]
^There is also a Morgan family burial plot in the church graveyard. The Morgan memorials here were renovated in the 21st century by the Lord Tredegar Memorial Trust.[4]
^A memorial in the churchyard commemorates Gwyneth Ericka Morgan (1895-c.1924). The daughter of Courtney Morgan, who is also buried in the plot, her disappearance in 1924, and the recovery of her body from the River Thames in 1925 was the subject of much speculation.[5] Gwyneth was originally buried in London, but was re-buried at Bassaleg after the accession of her brother, Evan Morgan, 2nd Viscount Tredegar, in 1934.[6]
