Smithfield United Church

The first all aluminum building ever constructed. It stands 30 stories tall and was built of aluminum panels in 1953. In 2001, Alcoa built a new building on the North Side and no longer occupies this landmark building.

This lovely church looks particularly out of place next to the massive office buildings surrounding it, but serves as an interesting reminder that this was once a residential area.

One of the best examples of Art Deco in Pittsburgh, this building is constructed with Indiana limestone and has a polished granite base, a dark copper roof, and marble walls in the lobby.

Intricately decorated.

An Art Deco edifice completed in 1932, this building was the city's tallest (and for that matter, the state's tallest) until the U.S. Steel Tower was completed in 1970. Today, it's the city's sixth tallest. The building is named for the Gulf Oil company, and the top of the tower is designed to resemble a step-pyramid/mausoleum which is illuminated at night with a coded system that shows the current weather with colors, or to celebrate the local teams' achievements and the holidays.

Built as a movie theater, the Harris plays both movies and live performances.
