New job at hand, so here's one of the first tests of one of the 4 entrances. PT, which makes darks really nice. Lot of work still needed to terrain (heathland with distant sea), roads, pallisades, buildings to build, and the entrances too. And then beautify with lots of Roman stuff....
Roads are kind of paved with slabs of sandstone, but I don't know yet how regular/irregular they should be.
