The Alfred P. Murrah Federal Building was a United States Government office building located in Oklahoma City, Oklahoma. It was the target of the Oklahoma City bombing, the most significant act of domestic terrorism on American soil(before 9/11).

The federal building was constructed in 1977 at a cost of $14.5 million, and was named for federal judge Alfred P. Murrah, an Oklahoma native. By the 1990s the building contained regional offices for the Secret Service, the Drug Enforcement Agency (D.E.A.), and the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF), and other agencies.

On the morning of April 19, 1995, Timothy McVeigh parked a rental truck with explosives in front of the complex and, at 9:02am, a massive explosion occurred which sheared the entire north side of the building, killing 168 people.

Following the investigation at the site and recovery of victims' bodies, the surviving structure was demolished with explosives on May 23, 1995. The Water Resources Board and Athenian Building, located across 5th Street from the building, were heavily damaged and later destroyed. The entire 3.3 acre site subsequently became home to the Oklahoma City National Memorial & Museum, a place to honor the victims, survivors and rescue workers, and to learn the impact of violence.

This is from the official website of the memorial. Today is the 13th anniversary of the bombing.
