Walkable demo
Castle courtyard
Walk a 44 by 40 metre castle bailey built from the Medieval Castle Construction pack: curtain walls and round corner towers, a gatehouse, a three-storey keep, cobbled yard with a well, forge, stables, market tables and an archery range.
About
One walled courtyard from 24 of the pack's 149 models, on plain grass in the outdoor preset with warm low sun and long shadows.
You enter under the gatehouse between two banner poles. The walls are 4 m curtain-straight segments on three sides with the gatehouse and short curtains on the front, and a round tower on every corner built from three stacked pieces: base, chamber and battlement. The keep at the back is the same idea: ground floor, upper floor at 3 m and battlement at 6 m. Cobble tiles pave the centre of the yard round the well. Stables, a hay rack and a woodpile take the west side; the forge hearth, anvil, water barrels and bread oven the east. A market awning covers a trestle table, two more tables with benches stand across the yard, and an archery range with two targets and two training pells fills the south-west corner.
Nothing moves: this pack ships without animation clips, so the gate and the well are static. Interiors, the wall walk and the siege engines in the pack are yours to add.
Every piece here is a published model from the pack, placed by hand. Walk with the keys or touch, and approach a piece to see it move if it has animation. Colliders, navigation and gameplay are yours to add.
Points of interest
Gatehouse
You enter under the 12 m gatehouse, which replaces three curtain segments in the front wall, between two banner poles. The other walls are 4 m curtain-straight pieces at 4 m steps.
Gatehouse (Medieval Castle Construction)The yard
Cobble tiles pave the middle of the courtyard with the well in the centre; the tiles are 0.2 m thick, so the well sits at y = 0.2.
Well (Medieval Castle Construction)The keep
Three stacked models: keep ground floor, keep upper floor at 3 m and keep battlement at 6 m. The corner towers stack the same way: round tower base, chamber and battlement.
Keep Ground Floor (Medieval Castle Construction)Forge
The forge hearth against the east wall with the anvil stump, water barrels and the bread oven beside the keep.
Forge Hearth (Medieval Castle Construction)Stables
A stable stall, hay rack and woodpile on the west side.
Stable Stall (Medieval Castle Construction)Market and tables
A market awning over a trestle table and bench, and two more trestle tables with benches across the yard.
Market Awning (Medieval Castle Construction)Archery range
Two archery targets against the west wall and two training pells in front of them.
