Fort. 1559-67 to designs by Sir Richard Lee, enlarged 1599-1601 to
designs by Arthur Gregory and an Italian engineer surnamed Baptist.
Converted into magazine 1668, Ordnance Laboratory 1827 and part of the

gatehouse, curtain wall and moat added 1599-1601. River front height-
ened, alterations to gatehouse and towers later in C17. Gatehouse:
coursed coarse ragstone walls either side of entrance with cross-loops,

rubble gatehouse projecting from two wider taller rear towers, all
brought up to greater height in C17 with double-splayed segment-
headed stone-dressed gun-ports in top stage of sides of gatehouse.
Wooden bell-cote over gatehouse with bell dated 1809. Recess immed-
iately over gate-arch, perhaps for coat-of-arms. Round-arched inner
gateway in line with inner tower walls with C20 balustrades on two
floors over, following C18 configuration. Curtain wall: rebuilt after
1625. Coursed ragstone with red brick parapet and wooden stakes

Coursed ragstone with some red brick rebuilding. Main block in centre

full width of magazine only. North-east and south-east towers:
Rectangular with brick parapets and round stair-towers towards Medway.
Various irregular loops and wooden mullioned windows. Magazine block:
Platband at half-height and crenellated parapet. End projecting round
towers and central projecting octagonal stair tower, all taller than

4 oculi on two upper floors and 2 round-arched windows on stair-tower,
all added before 1698. Various other loops. 3 round-arched doorways
at water bastion level, one in centre to wooden spiral stair, two outer
doorways to small side compartments under magazine. At the height of its
use in the early C17 the Castle was equipped with 'a demi-cannon, 7 culverin,
5 demi-culverin, a minion, a falcon, a saker and 4 fowlers with 2 chambers
apiece'. See A. Saunders, Upnor Castle, DOE Official Handbook, 1983.
