The Freedom Forum Journalists Memorial, located in Freedom Park, pays tribute to journalists who have died while trying to report the news. The memorial rises above the Potomac River with views of the Washington Monument, the Jefferson and Lincoln memorials and the National Cathedral. As of 2005, the names of 1,606 journalists from around the world are etched on the memorial's glass panels. The memorial is rededicated each year to include the names of journalists who died on the job the previous year.
