A stone clock tower, built in 1897 as a memorial to a member of the Pakenham family who were landlords in the area, stands at the top of the village near the former railway station.

Community relations
In recent decades Crumlin's population has increased as a result of an influx of residents from Belfast and surrounding areas. The majority of these residents are from an Irish nationalist background and as a result, Crumlin now has a nationalist majority. Until recently, Orange Order parades still occurred without incident and the main street in July is decorated with an Orange Arch which flies unionist flags from it. In 2012, The Twelfth celebration for a wider area was held in Crumlin for the first time in 12 years, a march which surpassed previous parades in terms of size and the number of bands and participants taking part. Some pre-march tension was evident and a Parades Commission determination appeared to rule in favour of the residents opposed to the parade based on its size and because they felt they weren't given adequate notice by the organisers of the parade. Talks were held between the residents and organisers, leading to the parade passing off peacefully. The agreement was heralded as a success and as a possible blueprint for other contentious marches.
