Converted from Crusader Kings 3, edited and adapted for Sims 4, this is a world building and interactive shell working as an Equestrian Center.
It has a small foot-print, and you can place deco around it - for example horse training equipment, tents (check out my converted TSM tents) or other deco.
Find it by searching for Jousting.
Place it on or off lots in empty spots in you hood using T.O.O.L by TwistedMexi.
You can use my Blowtorch mod to have a sims world emptied of modern stuff - read more here.
