Tower of London: Key Measurements

The Tower complex covers ~12 acres (4.9 ha). Here are the critical dimensions:

White Tower (Norman Keep, c. 1078)

• Height: 27.5 m (90 ft)
• Width (E–W): 36 m (118 ft)
• Length (N–S): 32.5 m (107 ft)
• Wall thickness: 4 m (13 ft) at base

Entire Castle Enclosure

• Length (E–W): 320 m (1,050 ft)
• Width (N–S): 145 m (475 ft)
• Perimeter: 1,080 m (3,540 ft)

Context

The White Tower is the central donjon; the outer walls and towers (e.g., Bloody Tower, Beauchamp Tower, Wakefield Tower) were added mainly 12th–14th centuries. The moat (now dry) once added ~50 m to the effective width.
