The Cathlapotle Plankhouse is a replica of the tribal house used through out much of the Northwest by the indigenous people. They were built using a post and beam construct out of logs and were cover by planks of cedar. Cathlapotle Plankhouse was built by volunteer and is a full size (37 ft. by 78 ft.) replica base on the archaeology found at the near by native village of Cathlapotle. The plankhouse is open for public visits only a few times during the summer. If you plan to visit check the schedule when you may visit.
