Stronghold Celt Castle-control plan
Stronghold strengthens Celt defensive positions and helps infantry remain near a Castle through repeated engagements. It is most useful when the opponent regularly attacks within the Castle’s range or when a forward Castle anchors a push.

Overview
Stronghold strengthens Celt defensive positions and helps infantry remain near a Castle through repeated engagements. It is most useful when the opponent regularly attacks within the Castle’s range or when a forward Castle anchors a push.
Plan and execution
Research Stronghold when your Castles are likely to see recurring close-range pressure, especially from ships or ground units that cannot safely stay outside their reach. Keep infantry near the Castle so they can benefit from its support and use the position to protect repairs, production, or a forward rally point. Pair the structure with a mobile force that intercepts siege and controls the ground outside its range.
Risks and adaptation
Many siege units can outrange or resist Castle arrows, so the technology does not solve a siege push by itself. Avoid researching it for an isolated Castle that the opponent can bypass; defend the outer approaches and keep counters ready.
