A cenotaph is an empty tomb or a monument erected in honour of a person or group of people whose remains are elsewhere. It can also be the initial tomb for a person who has since been reinterred elsewhere. Although the vast majority of cenotaphs honour individuals, many noted cenotaphs are instead dedicated to the memories of groups of individuals, such as the lost soldiers of a country or of an empire.
The word "cenotaph" in the English Language is derived from the Greek κενοτάφιον, kenotaphion. It is a compound word that is created from the morphological combination of two root words:   
Cenotaphs were common in the ancient world. Many were built in Ancient Egypt, Ancient Greece and across Northern Europe (in the shape of Neolithic barrows).
The cenotaph in Whitehall, London, designed in 1919 by Sir Edwin Lutyens, influenced the design of many other war memorials in Britain and in the British sectors of the Western Front, as well as those in other Commonwealth nations. Lutyens' cenotaph was chosen as a deliberately secular monument.

One depicts St George and the Dragon, the other depicts the sanctity of family life. Surrounding the sarcophagus are a number of bas-relief panels depicting scenes and people during the First World War.

A cenotaph in the UK that stands in Whitehall, London, was designed by Sir Edwin Lutyens  and replaced Lutyens' identical wood-and-plaster cenotaph erected in 1919 for the Allied Victory Parade, and is a Grade I listed building.  It is undecorated save for a carved wreath on each end and the words "The Glorious Dead", chosen by Lloyd George. It was intended to commemorate specifically the victims of the First World War, but is used to commemorate all of the dead in all wars in which British servicemen and women have fought. The dates of the First World War and the Second World War are inscribed on it in Roman numerals. The design was used in the construction of many other war memorials throughout the British Empire. The Cenotaph is used for annual Armistice Day and Remembrance Sunday Commemorations held every November where all political leaders and ex-prime ministers attend and lay a wreath in dedication to the fallen.

Although most notable cenotaphs commemorate notable individuals buried elsewhere, many cenotaphs pay tribute to people whose remains have never been located, particularly those lost at sea. Some such cenotaphs are dedicated to victims of the RMS Titanic whose bodies were not recovered after the sinking. Although Isidor Straus's body was recovered, Ida Straus's body was not, and a cenotaph at the Straus Mausoleum at Woodlawn Cemetery in the Bronx is dedicated to Isidor and Ida together. Its inscription reads: "Many waters cannot quench love—neither can the floods drown it."  ( Song of Solomon 8:7) The striking cenotaph of Major Archibald Butt, aide to U.S. President William Taft, is located at Arlington National Cemetery. 
In Inishmore, one of the Aran Islands of Ireland, drowning was formerly such a common cause of death for island fishermen that each family had a memorial to those lost at sea known as leachtaí cuimhneacháin (memorial cairns). Most were erected in the 19th century, although some date back to the eighteenth. A modern memorial was erected in 1997.  
In India, cenotaphs are a basic element of Hindu architecture, later used by Moghuls as seen in most of the mausoleums of Mughal Emperors which have two burial chambers, the upper one with a cenotaph, as in Humayun's Tomb, Delhi, or the Taj Mahal, Agra, while the real tomb often lies exactly below it, or further removed. The term chhatri, used for these canopylike structures, comes from Hindustani word literally meaning umbrella, and are found throughout the northwestern region of Rajasthan as well as in Madhya Pradesh and Maharashtra. In the Shekhawati region of Rajasthan, chhatris are built on the cremation sites of wealthy or distinguished individuals. Chhatris in Shekhawati may consist of a simple structure of one dome raised by four pillars to a building containing many domes and a basement with several rooms. In some places, the interior of the chhatri is painted in the same manner as the Haveli.
Cenotaphs have also been the subject of a number of illustrations including:
In the Internet age, virtual cenotaphs are common in the game World of Warcraft,   as well as in The Elder Scrolls series games though modding add-ons.
