I recently discovered a new seed that generates a village directly over a stronghold. You can actually dig straight down, without a single worry about hitting lava (You will hit a small, 4-block high cave, though. How to get there? Go to the village in the bottom-right corner of the map, the one spawned in the desert. Locate the tallest tower within it, and pretty much dig straight down inside it, in the middle section in line with the glass windows. It's exact co-ordinates are X:347, Y:82, and Z:344. You will hit the area at approximately Y:30. On your decent, you will pass through an iron and a coal vein. Be sure to have a pickaxe that can handle it!
