Try this.
Actualy pretty easy to do, that Archer most likely is just a flying unit that has been placed on top of the tower with its height increased to carefully match that of the tower.
If you wanted the archer to move you could just create a costum Pathing texture than blocks flying units around the walls of the tower to allow archer to move but still stay within the confines of the tower.

Set the movement type of the unit to none and movement speed to 0 (just to be sure).
