Poklop is a Czech word I came across today which means trapdoor or hatch. I’m not sure of its etymology, but I just like the sound of this word.
An alternative word for the same thing is padací dveře (lit. “falling door”). Related words include padací most drawbridge, (lit. “falling bridge”) and padací mříž portculis, (lit. “falling bar/grating/grid”).
