many memorial services and parades take place not only across the country, but in 26 American cemeteries on foreign soil (in France, Belgium, the United Kingdom, the Philippines, Panama, Italy, Luxembourg, Mexico, Netherlands, and Tunisia). It is also common practice among veterans to memorialize fallen service members on the dates of their death. This practice is also common in other countries when remembering Americans who died in battles to liberate their towns in the World Wars. One example of this is on 16 August (1944) Colonel Griffith, died of wounds from enemy action sustained in Lèves, the same day he is credited with saving Chartres Cathedral from destruction. In Judaism, when a grave site is visited, a small pebble is placed on the headstone. While there is no clear answer as to why, this custom of leaving pebbles may date back to biblical days when individuals were buried under piles of stones. Today, they are left as tokens that people have been there to visit and to remember. Americans of various religions and cultures may build a shrine in their home dedicated to loved ones who have died, with pictures of their ancestors, flowers and mementos. Increasingly, many roadside shrines may be seen for deceased relatives who died in car accidents or were killed on that spot, sometimes financed by the state or province as these markers serve as potent reminders to drive cautiously in hazardous areas. The Vietnam Veterans Memorial in Washington, D.C., is particularly known for the leaving of offerings to the deceased; items left are collected by the National Park Service and archived. Members of the Church of Jesus Christ of Latter-day Saints perform posthumous baptisms and other rituals for their dead ancestors, along with those of other families. Native Americans were not heavily concerned with the veneration of the dead, though they were known to bury the dead with clothes and tools as well as occasionally leave food and drink at the gravesite; Pueblo Indians supported a cult of the dead which worshipped or petitioned the dead through ritualistic dances. Islam Islam has a complex and mixed view on the idea of grave shrines and ancestor worship. The graves of many early Islamic figures are holy sites for Muslims, including Ali, and a cemetery with many companions and early caliphs. Many other mausoleums are major architectural, political, and cultural sites, including the National Mausoleum in Pakistan
