[1] Church records list rectors from 1181 (Geoffrey de Well) to 2001 (Robert Miles).

For centuries starting in the 1300s, Holy Trinity received support from the owners of Bolton Castle, the Scrope family.

The chancel arch and the capitals and bases of the two nave arcades are also work of this date.

"[6] Box pews were added in the early 19th century but the medieval character was retained.

[4] While it is not used for worship, the church remains open to visitors; some events are also held here, such as the flower festival, christenings, weddings and funerals.

[8] In October 2021, the church was one of 142 sites across England to receive part of a £35-million injection from the government's Culture Recovery Fund.

On the south side of the church are buttresses with three double lancet windows, the middle one of which is over a priest's door.

The nave contains the Scrope family pew with a 17th-century front and, at the back is a carved parclose screen from the early 16th century, that was moved from Easby Abbey at the Dissolution.

[10] In the east window of the south aisle are fragments of medieval stained glass.

Also in the church is a royal coat of arms dated 1701, and the standard of the Loyal Dales Volunteers.

[1] A wooden cupboard in the church is claimed to be a reliquary containing remains of Saint Agatha.
