found this by chance not long ago. Three villages within 100 blocks proximity to each other along a river. Great start for a survival and an amazing spot if you are more creative mode and want to build a huge village.
The villages are located (points to the well in each)
zombie spawner near far right village
skeleton spawned near far left village
320, 67, 571
Will add more as I find it. Please share anything else you find in the comments
