Often overlooked, doors are perhaps the most important feature of a building. They are the means by which we escape the often crowded and chaotic streets of the city. Every building has one (well, maybe except for the Raymond Street Jail which was accidentally constructed in 1836 sans front door), but some outfit this largely utilitarian feature with more panache than others. This collection highlights some the city's loveliest historic doorways, from the simple but classic columns of early 19th century Federal rowhouses to the gloriously geometric brickwork of Art Deco apartment houses, and everything in-between.

National Title Guaranty Company Building ARCHITECT: Corbett, Harrison & MacMurray DATE: 1929-30 STYLE: Art Deco The limestone and brick National Title Guaranty Company Building is notable for its strong massing and unusual details. The 16-story Art Deco style building was designed in 1929-30 by Corbett, Harrison & MacMurray, led by senior partner Harvey Wiley Corbett, a major proponent of the skyscraper as a modern urban form. Interspersed among the buttresses is a pierced limestone screen designed by the noted sculptor Rene Chambellan, which features stylized eagles, helmeted warriors and other elements. The building is a notable example of Art Deco commercial architecture, particularly with its strong vertical expression and unusual details.

185 Montague, ca. 1995. Built for the National Title Guarantee Company, the 1930 Art Deco building at no. 185 is a more modern standout among the Beaux Arts banking buildings that line this street. Designed by Corbett, Harrison & MacMurray, who also created Rockefeller Center, this Deco tower has sleek ziggurat towers at the top and delicate, but angular, tracery at the ground level. Some of the ornamentation has Aztec motifs and influence. Given these decorative features, it is almost appropriate that the former banking building is now a location of the Mexican-themed restaurant, Chipotle.
