Maesyronnen Congregational chapel was formed in 1692 and has important associations with the history of non-conformity in Wales. Meetings are said to have started with Vavasours Powell's ministry in 1640 and an independant chapel stemmed from the 1649 Act for the better teaching of the Gospel in Wales. It was formed as an offshoot of the Baptists of Llanigon and Hay.

Various ministers are recorded before 1658, and between 1672 and 1682 Henry Maurice probably used this sub-medieval longhouse-derived farmhouse for unauthorised meetings. Oliver Cromwell is said to have attended a meeting here. The chapel was adapted for worship by dissenters and registered at Prestiegne in 1696. The chapel is also associated with Dr Abraham Parry, FRS editor of the first encyclopedia, and was leased with cottage and garden by the successors of Sir Humphrey Howarth to the chapel elders by an indenture of April 1720.

The chapel was refurbished around 1985. It was built 1696 in the Vernacular style with its entrance in the long-wall. It houses a number of wall monuments of interest to the history of non-conformity in the area.
