Harrow School's memorial to the dead of the First World War is named as one of the country's most outstanding war memorials, writes Michael Pickard.

In his new book A Century of Remembrance, author Derek Boorman lists a hundred memorials commemorating those who gave their lives in 20th century conflicts, from the Boer War (1899-1902) to the first Gulf War of the early 1990s.

Among them is Harrow School's impressive War Memorial Building, designed by Sir Herbert Baker and opened in 1926 by Prime Minister Stanley Baldwin and dedicated by the Archbishop of Canterbury, Randall Davidson, both of whom were Old Harrovians.

The building's main feature is a shrine dedicated to more than 600 masters and former pupils who died for king and country from 1914 to 1918, whom an inscription bescribes as "valiant hearts" with knightly virtue.

The names of Old Harrovians who fell during the Second World War are listed on bronze tablets on the ground floor.

The Crimean War of 1854-56 and the Boer War also have memorials at the school on the Hill, and can be found in the chapel that was built in 1855.

Derek said that he took several factors into account when choosing which memorials should be included in the collection.

It was most important that tributes to many different wars were featured, and that the memorials showed the work of various artists.

Some artists such as Sir Edwin Lutyens, who designed the Cenotaph in Whitehall, are responsible for many memorials, but it was decided to offer a wide variety of examples rather than to focus on several more prominent sculptors.

Various forms of memorial was also important to the author, and A Century of Remembrance features statues, chapels, arches and gardens, as well as the more traditional crosses.

The book runs in chronological order, starting with a Boer War memorial unveiled on November 5, 1904, with the newest featured being the Animals in War memorial installed in central London a year ago.

All proceeds from the book are being donated to the War Memorial Trust, which works to protect the UK's 65,000 war memorials.
