São Jorge Castle Fortifications — Walls, Towers & Defenses

Defensive elements explained

• Curtain walls: Multiple concentric lines — visible in the first wall line and inner courtyards.
• Towers: Platforms for surveillance and artillery; note the differing profiles from medieval to post-medieval rebuilds.
• Battlements & embrasures: Designed for both archers and later for firearms — adaptation shows technological shifts.

Walk this route

1. Enter via the main gate (entrance_00) and inspect the moat/bridge if visible.
2. Climb to the catwalks and towers for defensive vantage points (catwalk_00 series).

Tip: Bring a zoom lens for masonry details — stone tooling marks tell a story.
