Caerphilly Castle has had a £5m investment into conservation and repair of the structure - from late October '22 the scaffold and sheeting that protected the works will be removed. Caerphilly Castle is the biggest castle in Wales, and second biggest in the UK. Wales’s very own Leaning Tower, even wonkier than that of Pisa — courtesy of Civil War gunpowder is probably the castle’s best-loved feature.

Ruperra Castle was built in 1626 by the Steward to the Earl of Pembroke, Sir Thomas Morgan. It's actually a mock castle – a residence with a castle-like appearance rather than a fortress. Now, the castle lies in ruin and is quite something to behold.
