An underwater shipwreck: a wooden galleon on its side on the ocean floor, holes in the hull, coral and seaweed growing on it, treasure chests spilling gold, and fish swimming around

A steampunk airship with a wooden hull, large brass propellers on each side, a balloon made of patchwork fabric above the deck, hanging ropes and ladders, and a glass-enclosed bridge at the front
