*** Sandstone Version *** The Grand Vestibule is the massive ruined entrance section of a circular tower, rotunda or acropolis. From end to end the remnant is just over 11 inches wide and is 10 inches high at its tallest point. The two story structure opens out onto a small balcony above the doorway. The Grand Vestibule may be combined with other pieces in the Hall of Heroes collection to mark out a larger ruined building or stands alone as an imposing piece of terrain.
