The Hawarden Visitors' Hand-Book
Next to this last is the Chapel, or rather Sacrarium, with a cinquefoil- headed doorway, and a small recess for a piscina, with a projecting bracket and fluted foot. Against the West wall is a stone bench, and above it a rude squint through which the elevation of the Host could be seen from the adjoining window recess. Of the two windows, one is square, the other lancet-headed. The altar is modern. There is a mural gallery in the thickness of the wall running round nearly the whole circle of the Keep, and with remarkably strong vaulting.
Descending from the Keep and inclosing the space below, were two walls or curtains, as they are technically called. That on the N. side, 7 feet thick and 25 feet high, is still tolerably perfect, and within it lay the way between the Keep and the main ward. Of the South curtain only a fragment remains attached to the Keep.
