The clearance of the back two compartments of the castle has taken much longer than the others, simply because they aren’t accessible by the minidigger and there’s not enough room for more than a couple of workers. Our luck continues with the floors, which are all concrete, making clearance much much easier than suspended floors.
If you want to help with castle or bridge we have two volunteer fortnights in May 2020 and September 2020 – available here.
