A chapel of ease (or chapel-of-ease) is a church building other than the parish church, built within the bounds of a parish for the attendance of those who cannot reach the parish church conveniently.
Often such a chapel of ease is deliberately built as such, being more accessible to some parishioners than the main church. Such a chapel may exist, for example, when a parish covers several dispersed villages, or a central village together with its satellite hamlet or hamlets. In such a case the parish church will be in the main settlement, with one or more chapels of ease in the subordinate village(s) and/or hamlet(s). An example is the chapel belonging to All Hallows' Parish in Maryland, USA; the chapel was built in Davidsonville from 1860 to 1865 because the parish's "Brick Church" in South River was too far away at 5 miles (8 km) distant. A more extreme example is the Chapel-of-Ease built in 1818 on St. David's Island in Bermuda to spare St. David's Islanders crossing St. George's Harbour to reach the parish church, St. Peter's, on St. George's Island.
Some chapels of ease are buildings which used to be the main parish church until a larger building was constructed for that purpose. For example, the small village of Norton, Hertfordshire, contains the mediaeval church of St Nicholas, which served it adequately for centuries; but when the large new town of Letchworth was built, partly within the parish, St Nicholas's became too small to serve the increased population. This led to the building of a new main church building for the parish, and St Nicholas's became a chapel of ease.
