In 1867 it was separated into two Circuits with the river as the dividing line. Wesley Chapel, in Priory Street, which had been opened the year before, became the head of the new Circuit with 12 Chapels. 

The advantage of the new arrangement was soon evident in the many new chapels which shortly appeared. 

One of the first in the Wesley Circuit was a Mission Chapel in Wilton Street (now Wilton Rise).  It was built in 1872 at a cost of £800 and was put there to minister to the needs of those employed at the nearby Railway Works.
