Megadungeon maps

[ChudoJogurt]

Not sure if this is a right place to ask, but does anyone know a place one could find a map for a really big dungeon?

Preferably something spanning several levels (building levels, not character levels).
Could be official, could be third party, could be fan-made, I just need a nice map to put in roll20.

I have the Rappan Athuk book, but unfortunately maps there seem to be piecemeal, and assembling them bit by bit seems like a lot of work. I was hoping to find it as one big map, or one-map-per-level sort of thing.

Worth noting that the map displayed there is only 1/16th of the dungeon.

Raging Swan Press has some free map packs that might be of use to you.

Undermountain is probably as large or larger than WLD, and Pathfinder’s Emerald Spire is advertised as a superdungeon.

Google "Dyson Logos megadelve". His art style is pretty popular these days and it's definitely a big dungeon.

Otherwise spend 5 bucks on the roll20 store and pick up a nice set of maps. I recommend Gabriel Pickard.

If you just want maps without a dungeon or indeed system attached you could try dragonsfoot

This reddit forum has a lot of maps, mostly small ones. I grab stuff from it frequently.
Might be some big stuff there.
