Minecraft medieval map

Hello everybody, i have these maps: drachenfells, kingslanding and shingashina world. I love these maps because they are very long and have full interiors, not like other maps that the interiors are not made. I ask if somebody know about other mapa with a size similar than this and with fully interiors. thanks everybody¡
The version must be 1.12.2 as maximum, because i have a lot of mods and i can´t update.
