Dating to 1891, over its history the First Regiment Armory Annex (better known as simply The Armory) was been a place for military marching drills and target practice, a concert hall, and a beer-brewery warehouse. A 2006 renovation of The Armory gave birth to the Gerding Theater inside, headquarters for the city's leading theater company: Portland Center Stage. We talk with architects Stepen Domreis and Craig Mendenhall of GBD Architects about balancing historic preservation with ambitious sustainability goals, and with Portland Center Stage artistic director Marissa Wolf about the upcoming 2019-2020 season and how great theater is a melting pot of stories and ideas.
