Alne mill weir.
This weir, seen here coping well with all the rain of the last few days, controls the level of the River Alne on its way to join the Warwickshire Avon via the River Arrow.
The Mill itself was mentioned in the Domesday Book and at that time was valued at five shillings and by 1291 had increased in value to six and eight pence. Converted in 1989 into luxury apartments it's probably worth at tad more by now.
Off to LPH tomorrow, after I've packed all my kit away.
