Architecture at a Glance
- Plan logic: a rectangular core with projecting turrets.
- Vertical circulation: a principal spiral stair and secondary stairs.
- Defensive grammar: limited apertures; mass as deterrence.
Materials & Making
- Caen stone dressings articulate openings and edges.
- Ragstone rubble cores supply bulk and durability.
- Mortars and limewash once softened the stone’s finish.
Roles Across Time
- Royal residence to symbolic fortress.
- Armoury and administrative spaces.
- Today: an interpretive anchor for the whole site.
Curious Detail
- Evidence suggests early limewash may have given the tower a lighter tone—hence the “White Tower” name.
- The chapel of St John is one of the best-preserved examples of a royal Romanesque interior in England.
Visiting Tips
- Pace your ascent—stairs compress crowd flows at pinch points.
- Read masonry like a palimpsest: note patches and repairs.
- Seek quiet moments in St John’s Chapel to absorb proportions.
Bottom Line
The White Tower compresses conquest, ceremony, and craft: a Norman keep still doing the work of storytelling.
