16 Room House is one of a number of ruins located near the San Juan River in the area around Bluff and Mexican Hat, Utah. Many of these ruins are only accessible from the river. 16 Room House is an exception – you can get to it by driving county roads. 16 Room House is not a large ruin or especially well preserved, but it is an interesting Pueblo III, Mesa Verdean style ruin. As is typical of many Pueblo III ruins, 16 Room House seems to have a very “defensive” nature.
