The course of La Rambla was originally a sewage-filled stream, usually dry but an important drain for the heavy rainwater flowing from the
Collserola hills during spring and autumn. (, from the
Arabic 'sand', is Catalan for "
wadi". The name of the city of
Ramla in Israel is derived from the same origin). It separated the walled city on its north-east bank from the settlements of El Raval ("the suburb") on its south-west. In the year 1377, construction started on an extension of the city walls to include La Rambla and El Raval. In 1440, the stream was diverted to run outside the new walls, and La Rambla gradually started turning into a street. Over the next few centuries, La Rambla became an established center of Barcelona's urban life, serving as a long wide thoroughfare used for festivals, markets, and sports. Several large religious establishments were also built along the street during this period. These include the Jesuit Bethlehem monastery and college (1553), of which just the later church remains; the Carmelite St. Joseph's monastery, on the site of the current
Boqueria market; and a Capuchin monastery at the lower end of the street. During the late 19th century, many Catalans who had made their fortunes from trading in slaves or owning slave plantations in
Spanish America returned to Barcelona after the abolition of slavery in 1886. Several of them invested their newfound fortunes in constructing opulent mansions in areas such as La Rambla. German historian
Michael Zeuske has argued that the street was "built on the backs of slaves", although
The Guardian claimed that "[this] is an exaggeration." Various conflicts over recent centuries took their toll on La Rambla's religious buildings, most notably the St. James's Night riots in 1835, when revolutionaries burned the monasteries and churches and killed a number of friars; and the
Spanish Civil War in 1936–39, when Barcelona came under the control of
anarchists who again targeted religious buildings and personnel, as well as being damaged by artillery and air attacks on the area from pro-
Franco forces. Until 2010, the was the site of an open-air market for caged birds and other small pets. However animal protection laws made it difficult for the market to continue. After years of fighting the legislation, the market was forced to close. On 17 August 2017, many people were struck by a
van deliberately driven down the sidewalk on La Rambla in a terrorist attack, causing 16 deaths and at least 300 injuries. ==Sights==
