Drumbo is a small village, townland and civil parish in County Down, Northern Ireland. It is about south of Belfast city centre, east of Lisburn and west of Carryduff. It is in the historic barony of Castlereagh Upper. The townland has an area of. The 2001 Census recorded the village's population as 408. The village is set on the edge of a ridge where the drumlin country of County Down starts to descend into the Lagan Valley. It is laid out around a junction of routes meeting at the front of the Presbyterian Church, which is a listed building. The current church building is beside the site of the medieval parish church, the foundations of which can be seen in the graveyard, as can the lower half of the truncated Drumbo round tower, a scheduled historic monument. The round tower was originally built here to take advantage of the panoramic views over the Lagan Valley. At the time of the tower's construction, these views would have been useful in spotting oncoming Viking raiders. The tower formed part of a monastery. The area is designated in the DOE area development plan as an 'area of outstanding scenic amenity value'. The village lies on the southern edge of the Lagan Valley Area of Outstanding Natural Beauty, while the northern part of the townland lies within it. The present village has expanded to the south-east along the ridge away from the church and graveyard, with much of the built form developing in the late 20th century. The church buildings still occupy a prominent site in the middle of the settlement. Drumbo functions as a small service centre and facilities include Drumbo Presbyterian Church and Hall, a community hall and a playground and playing fields at Front Road. A feature in the heart of the village is a wrought iron pump with a distinctive double wheel crank mounted at the junction. This forms the centre of the village adjacent to the presbyterian church, round tower and village hall. Directly opposite this pump is the building which was for many years the post office for the village. A short distance South of this a blacksmith's foundry operates.
