Interior of a mausoleum on Mausoleum Circle in section 40 of Mount Olivet Cemetery in Washington, D.C., in the United States in 2014. This structure features single crypts on either side of the aisle. An altar-like structure at the far end of the mausoleum has a "blank" arch beneath it. A stained glass window featuring an angel is in the rear wall, light by sunlight from behind. Family members (the only ones with access to the mausoleum) have placed a vase with flowers on the shelf.
