The chess opening trap known as the Noah’s Ark Trap falls under the Ruy Lopez opening category. This term refers to a set of traps within the Ruy Lopez that involve black pawns trapping a white bishop on the b3-square.
It is unclear where the name comes from. It could be due to the resemblance of the black pawns on a6, b5, and c4 to an ark, or it may have originated from the idea that the trap is ancient, dating back to the time of Noah’s Ark (or at least to the time when the modern chess rules were established).
I was happy to find a real game with this exact trap in our database:
