Heard Building, Historical building in Phoenix, Arizona

The Heard Building is a seven-story reinforced-concrete high-rise in downtown Phoenix. Its pale upper facade is divided by vertical white piers that rise above the flat roof, with recessed windows between them; the dark ground level holds storefronts, including one under a "DOWNTOWN" awning. A "NOW LEASING" sign stands near the right corner.

Construction began on September 2, 1919, financed by Dwight B. Heard and the Commonwealth Investment Company and designed by Llewellyn Adelbert Parker. Completed in 1920, it was Phoenix's first high-rise and Arizona's tallest building until the Luhrs Building in 1924. After the 1910 Adams Hotel fire, Heard built it with a reinforced concrete frame. It housed The Arizona Republic and Phoenix Gazette until 1948 and was sold in December 1951 for $710,000.

The building is named for Dwight B. Heard, the investor and publisher who financed it with the Commonwealth Investment Company. From 1920 to 1948 it housed The Arizona Republic and the Phoenix Gazette, and in 1930 the newspaper's radio station KTAR began broadcasting from a 1,000-watt transmitter on the seventh floor, its call sign standing for "Keep Taking Arizona Republican". In February 2018 the Swiss duo NEVERCREW painted three murals, "El oso plateado and the machine", on the walls as a tribute to the building's past and the extinct Mexican grizzly.

The Heard Building is a seven-story office block at Central Avenue and Monroe Street in downtown Phoenix, with dark storefronts at street level and a "NOW LEASING" sign at the corner. It is a working commercial building rather than a museum, so the interior is not open for sightseeing; the facade, the vertical white piers and the rooftop antenna mounts are seen from the sidewalk.

In February 2018 the Swiss artist duo NEVERCREW painted three murals on the building's walls, titled "El oso plateado and the machine", a tribute to the building's past and to the extinct Mexican grizzly. In 1922 Bill Strother, the "Human Spider", climbed the facade and sat on top of the flagpole.
