It is a Grade II listed building[1] and is the oldest purpose-built synagogue in existence in Wales.

[5] In the 1980s, the synagogue was closed and the building was sold and became the Merthyr Christian Centre.

Essential repairs were undertaken in 2021, part funded by Cadw, to make the building weather-proof.

Unlike the "simple," "charming" Gothic synagogues that once graced Llanelli and Pontypridd, however, the synagogue of Merthyr Tydfil is a "Disneyland" fantasy of a building that architectural historian Sharman Kadish calls a "double-turreted Gothic folly" of a building.

It is crowned by a high gable two storeys tall, capped with stone finials.

A double stone staircase rises to the Gothic entrance door.
