Time for a #NerdyMouseAlert. Look away now if you don't want minute technical detail: wonderful C15 piers to the arcades. Four thin engaged shafts separated by cavetto (hollow) moulded strips. You can feel the centuries.. #HolyTrinityAbbotsLeigh #NorthSomerset #StonemasonryMonday

Time for a #NerdyMouseAlert: look away now if you don't like minute technical detail

Chancel arch #StCatherineBatheaston #Somerset for #StonemasonryMonday. Broaches bridge the chamfer of both arches and the square section below and yet the arches are Early English, capitals C19

Time for a rather extended #NerdyMouseAlert from #StJohnKeynsham #Somerset for #WallsOnWednesday: Look away now if you don't like minute technical detail #KeynshamChancel Part II of IV: Tiny pent roof over the projection allowing space for the rood stair (east of north chapel)

Time for a rather extended #NerdyMouseAlert from #StJohnKeynsham #Somerset for #WallsOnWednesday: Look away now if you don't like minute technical detail #KeynshamChancel Part I of IV: The fun of piecing together historical changes to a church through clues etched in the walls

Not wonky, not scrumpy (as Mouse's earlier post suggested), but deliberate... #NerdyMouseAlert

This is a reused arch (#Spolia) curtailed and slightly rotated to make it narrow enough to fit the porch. To do that the jamb and screwback are raised on the right #StMartinNorthStoke

Quick #NerdyMouseAlert. Look away now if you don't like the technical detail...

The piers of the north arcade are typical of the Perpendicular period. Engaged columns separated by a moulding that extends around each arch #StMaryWestwood #Wiltshire for #StonemasonryMonday

Time for a #NerdyMouseAlert (new #), look away now if you don't want minute technical details. Spur at the base of each of the aisle pier corners. Small half moulding above (what is normally) a curved surface. Often seen as a detail on C13 masonry #StMaryPortbury #NorthSomerset #StonemasonryMonday

Time for a #NerdyMouseAlert. Look away now if you don't like minute technical detail. A pilaster strip sits in a channel in the wall. It may be laid with each stone course or cut in later #PilasterStrip #StLaurenceDecoration #WallsOnWednesday #StLaurenceBradfordOnAvon #Wiltshire

Ready for a #NerdyMouseAlert? Look way now if you don't want minute technical detail #StCatherineBatheaston #Somerset for #FerrousFriday #PintlesInAction

South door: Part II; The strap fits over the planks and under the framing. The gudgeon on the end fits over the drive pintle

Time for a rather extended #NerdyMouseAlert from #StJohnKeynsham #Somerset for #WallsOnWednesday: Look away now if you don't like minute technical detail #KeynshamChancel Part IV of IV: Blocked Early English pointed windows. The remaining window is a later Victorian insertion

Time for another #NerdyMouseAlert, look away now if you don't want minute technical details. Where an arris meets a chamfered edge you may find a bridge or broach to soften the join. This tiny cushion capital with shaft and shaft ring is Romanesque #StMaryPortbury #NorthSomerset

Reeling from the lack of Mouse posts today? To make up Mouse give out a #NerdyMouseAlert: look away now if you don't like minute technical detail. Tiny broach at the base of each upright of the #Piscina fenestella bridging the cavetto moulding and square section below it joins

South door: Part I; Closest, the outer framing of door. Rear the planks of the door. The former recessed to create a rebate.

This is the sort of nerdy detail we need more of. More #NerdyMouseAlert please!
