Ralph of Caen, watching the city from the Mount of Olives, saw “the scurrying people, the fortified towers, the roused garrison, the men rushing to arms, the women in tears, the priests turned to their prayers, the streets ringing with cries, crashing, clanging and neighing.” The Crusaders took over many of the cities on the Mediterranean coast and built a large number of fortified castles across the Holy Land to protect their newly established territories (28.99.1), while also establishing churches loyal to Rome.
There is no specific author listed, however The Metropolitan Museum of Art is a known credible institution. The intended audience for this web page would be people who want to go see artifacts from the crusades. This site is similar to the Time line for the Crusades, however has a catalog of relics form the crusades.
