My poor medieval people are taken from our medieval Europe (Germany to be more specific) with an entire settlement to another world (think: cut a few square kilometeres of land and paste it somewhere else).
Their new location isn't quite safe. There are lots of dangerous creatures outside, some of them weird or mythical. This and other reasons forced the people to make the village tight and defendable. I thought about a palisade, but if you have other ideas, they're also welcome. I am wondering what area will the village cover. There are fields around the village which would be nice to include inside the palisade, but it depends on the necessary length of it.
- I assume there are around 100 people in the village, three quarters of them are working age (if you have some solid arguments against those numbers they can be slightly tweaked).
- The fields area necessary for those people and will be around 50000 square meters.
- There must be place for: a church (an old one, built before they were taken), a windmill (or another simpler structure allowing milling of flour), one or two wells to provide water (there are no rivers nearby), houses for every family, plus some spare places for unexpected situations.
- The villagers are ready to personally protect the settlement if the necessity occurs.
- Wood is easily accessible (though not without risk) from a forest nearby, but stone is quite rare and valuable.
The question itself
How much area will the village cover?
