nave extended in the C14, 1723, east part of nave rebuilt.
Nave: north side with one restored square-headed window with two trefoil-headed lights to left and two similar windows to right of blocked C11 north doorway
'One of the three oldest churches in Herefordshire' can be found at Hatfield, which still has remnants from its C11 core, such as the blocked north doorway and herringbone masonry. The nave was extended in the C14, the same time when the chancel was rebuilt, and the east area of the nave was rebuilt in 1723. Restored in 1878 and 1903, the church building was grade II* listed on 11th June 1959.
West porch possibly retains some C14 timberwork with curved braces to outer entrance forming a pointed arch.
The chancel has a restored square-headed window with two trefoil-headed lights to the north and a similar window possible of C14 to the south side.
The four chamfered posts of the bell turret revealed in the lobby may be of a medieval date.
Two-centred headed chancel arch possibly of the C13
Fittings: late C11 font
This font inside the porch/bell tower at St. Leonard's church in Hatfield looks very old, and might be an early Norman font.
