Westminster Abbey was born in the middle of the Viking invasion and conquest. Edward the Confessor, King of Wessex, took the English throne in the early eleventh century.
The king built a church adjacent to the religious centre of London that began to be called "West Minster", to distinguish it from St Paul's Cathedral (the east minster), located in the City of London. 
 
Unfortunately, when the original church in the site was consecrated on 28th December 1065, the King was too ill to attend and died a few days later. His mortal remains were entombed in front of the High Altar. After the Battle of Hastings in 1066, William the Conqueror was proclaimed King at Westminster Abbey and so it has been with all the consequent monarchs. 

Currently, the abbey is a place of worship and a must-see for all people who want to get to know London.  
Today, you can visit the abbey for tours from Monday to Saturday, and for services on Sunday.
