Stockport Council is to repair and restore the grade-2 listed stone gateway and boundary walls to St Mary's Church, Stockport town centre.
The poor condition of the gateway, located between the church and the market hall, resulted in it being highlighted on the National Register of Heritage At Risk compiled by English Heritage.
The council has received an English Heritage grant of £48,000 towards the £60,000 cost of the work, expected to be complete by March.
St Mary's Church itself is currently undergoing stonework repairs to the tower and its interior including the removal of pews, installation of kitchen facilities and new toilets.
Cllr Iain Roberts, executive member for economic development and regeneration, said: "The historic gateway and church walls are part of a closed churchyard and therefore the council is responsible for the repairs and maintenance.
"When repaired and restored, the gateway will act, both functionally and symbolically, as a perfect link between the church and the town. Improvements to the church will enable wider community use for a greater number of activities which will also strengthen the links between St Mary's and the town centre."
The work will contribute to the on-going conservation-led regeneration of Stockport's historic town centre.
