LEGO part 2642 - Dark Gray Baseplate, Raised Platform 16 x 16 x 2 1/3 Ramp at BrickScout
A shrine to all raised baseplates - The Brothers Brick | The Brothers Brick
I made a 90's style Pirates/Islanders/Adventurers themed MOC, called Corsair River Ruins. Complete with falling boulder trap! I wish Lego would bring back raised baseplates! : r/lego
