Dozens of cenotaphs and memorials to Second World War soldiers were erected. Eventually, to avoid vandalism, the cenotaphs within the mausoleum were encased in brick. Congress erected the monument in 1839 anyway, establishing the tradition of erecting cenotaphs. Most of the graves are burials, some are ritual fences - cenotaphs. The inner chamber of the Taj Mahal contains the cenotaphs of Mumtaz and Shah Jahan. On the marble dam are six exotic cenotaphs and a Shiva temple in the centre. Some graves do not contain a skeleton, but grave gifts (cenotaphs). These are the only cenotaphs erected since 1876. Granite memorial benches were also created for the three rescuers killed and serve as cenotaphs. The calligraphy found on the marble cenotaphs in the tomb is particularly detailed and delicate. It now serves as the pre-eminent war memorial of 76 cenotaphs in Canada. Numerous cenotaphs or chhatris dot the vicinity of the fort and the Betwa river. The central ritual at cenotaphs throughout the Commonwealth is a stylised night vigil. The ancient city of Abydos was the location chosen for many of the cenotaphs. These include the Ahar Cenotaphs outside Udaipur, and Bada Bagh near Jaisalmer.
