We also say in the middle or in the centre (of something).
Use on when there is a surface underneath.

ON is often used with flat surfaces (the walls, the floor, the beach) but also furniture (the table, the bed) and the body (your back, your face).

Use at with buildings and "points in space".

AT is often used with points in space, addresses and buildings (especially with the verbs arrive, meet and wait).
