The church of All Saints is located S of the village of Monk Sherborne, N of Basingstoke in N Hampshire. The name dervies from the presence of Pamber Priory, 2.33km to the N, in the same parish. The building is faced in flint, some of it laid in a herringbone pattern. It comprises a chancel and an aisleless nave with a timber N porch and S vestry. A bell turret rises in one stage with a pyramidal spire over the hipped end of the nave roof. Next to this, on the N side, is a substantial stone stair turret. The 12thc. origins of the church may be seen externally in a blocked window in the N wall of the chancel and the carved N doorway. Internal features belonging to the 12thc. include the chancel arch, the remains an E arch (which may have formed the entrance to an apse) and a reset pillar piscina. The font may belong to the early 13thc. Several architectural fragments of uncertain origin have been reset in the E wall of the chancel.

In 1086 (Domesday Survey) Monk Sherborne was held by Hugh de Port. No church was mentioned, but one had certainly come into existence by c.1120-30 when Hugh’s son, Henry de Port, granted the advowson and tithes to his new Benedictine foundation, Pamber Priory. This dependency of the abbey of St. Vigor at Cerisy-la-Forêt in Normandy retained the advowson until its suppression in 1452. In 1462 Edward IV granted the Priory and all its possessions – including the churches at Monk Sherborne and Bramley – to the hospital of St. Julian or God's House in Southampton, which belonged to Queen's College, Oxford.

An early 19thc. watercolour shows a bell-turret with two weather-boarded stages rising above the hipped end of the nave roof (Historic England Archive, red boxes). The church was restored in 1852 and in 1888-89 (Bodley & Garner) (Hampshire Chronicle, 30 March 1889, 5 and 27 April 1889, 8).

In 1890, during a visit by Hampshire Field Club, ‘most attention was attracted by the font which, like the church, has been “restored”. The bowl had been found resting on a pillar, but there were indications that it had been originally supported on three short pillars, and these were now supplied’ (Hampshire Antiquary & Naturalist, 1891, 117).

The crowstepped surround of the N doorway is an unusual feature without exact parallels. Lengths of billet were used to create decorative triangular compartments around the doorways of several Romanesque churches in France. At Le Mans cathedral and St Symphorien, Azay-le-Rideau, this appears in the same context as opus reticulatum. It is unclear, however, whether the opus reticulatum at Monk Sherborne is genuine. In its present form it appears to be inscribed, possibly on the basis of surviving evidence.

The surviving capital and impost block of the apse arch are closely comparable with those of the chancel arch. They are presumably by the same workshop, and contemporary in date, c.1120-30. The doorway is of a similar date. This work corresponds with the period when All Saints was granted to Pamber Priory (see History).

In both doorway and chancel arch, scallop capitals are rendered in an unusual manner suggesting that the conventional form was not properly understood by the sculptors, or that they were developing an individual variant.

The basin of the pillar piscina may date from c.1175.

The font has been variously dated, but probably belongs in the first quarter of the 13thc.
