All Saints Parish Church stands on the western side of the High Street, with Castle Close behind it, in the market town of Northallerton, the administrative capital of the North Riding of Yorkshire. The first church on this site probably dated to the seventh century, although no documentary evidence exists of any building before the present one. That first, probably wooden, building is said to have been founded by St Paulinus, first bishop of York (died 644).
The present building dates to the ninth century, and fragments are occasionally unearthed. The majority of the Perpendicular church was rebuilt in the fifteenth century, but the Norman north aisle arcade (of about 1120) has survived. The south aisle arcade was added about seventy years later. The tower collapsed in 1318, when Northallerton was sacked by the Scots. It was replaced by the present tower in 1420. The interior was extensively refurbished in the late 1800s.
