How Long Did It Take to Build Château Pèlerin (Atlit)?
Short answer: about 2 years, from 1218 to 1220. This period is our own estimate of the main building phase; the sources do not give one clear start and end.
Pilgrims are said to have helped build it, hence the name Pilgrim's Castle. It was never taken in a siege.

What the sources say about the building period
Construction began 1217–18 (Templars with pilgrims); sieges 1220 and 1265; abandoned 1291. Wikipedia Secondary source
Stone and crew in numbers
- Country and type
- Israel, castle
- Stone in the walls
- 50,000 to 90,000 m³ Estimate
- For comparison
- about 28 Olympic pools of stone, or 7,000 truckloads
- Average crew
- about 4,186 workers (model value: the crew that would need exactly this long, working without a break)
Volume basis: outer wall 6–6.5 m thick, 15–16 m high; inner wall 12 m thick, over 30 m high; two towers 21 x 27 m; length of the cross walls assumed. Checked against measurements. Our estimates come from published dimensions and are shown as a range. The result is a simple model, not a measured fact.
Where the stone came from
Quarried on the spot. The builders cut stone at several places along the Atlit ridge at once, which also created a 2.1 km rock-cut cliff as the eastern defense. Journal of Medieval Military History: The External Fortifications of Atlit Castle Academic source

Legend: tradition, not evidence
Pilgrims built the castle with their own hands, which is why it was called Pilgrim's Castle.
What we know: The Templars began the castle in 1218. Wikipedia says the name probably comes from pilgrims who volunteered their labor. The castle was never taken in a siege and was evacuated by sea in August 1291.
