Architect Wirt C. Rowland played an integral role in crafting the city's historic skyline with his designs for the Buhl, Penobscot, and Guardian buildings. Rowland's design for the Buhl Building (1925) included a Gothic Revival design, with a blend of Romanesque accents. Renowned Art Deco skyscrapers include Rowland's Penobscot (1928) and Guardian (1929), and John M. Donaldson's David Stott Building (1929). Architectural tiles made from Pewabic Pottery by American ceramist Mary Chase Perry Stratton are a prominent feature in the Guardian Building's facade and decor.
