I built the imperial fort for the recent Surrey Museum’s LEGO® Pirate exhibit in 2010.
While the fort is a unique creation, the architectural style is loosely based on a Dutch fort I visited in the north of Brazil, Fort Natal.
Both the stone and LEGO forts have the same thick wall for repelling cannon balls and heavy crenels to hide the troops and cannons.
While the fort was based on reality, the whirlpool was entirely fictional 🙂
The motorized whirlpool spun along side the Coral Castle I build. Random fact; I used approx 800 1×1
round white plates and 500 round bricks to make the coral, mostly jammed sideways into the open holes of Technic bricks. The best part is that I didn’t have to do it alone. I had many hours of help from fellow builders Pierre and Pascal.
You can also see a great video of my whirlpool spinning here.
