a borough of Greater London on the Thames; contains Buckingham Palace and the Houses of Parliament and Westminster Abbey
"The historic district of Westminster along the Thames is home to iconic landmarks like Buckingham Palace and the Houses of Parliament."
The abbey of Westminster
"The bells from Westminster rang out across London to announce the coronation ceremony."
The name Westminster comes from the medieval abbey located there and combines the Old English words for "west" and "minster," a type of large church or monastery. It was formed by placing the direction west before the term minster, which originally referred to these significant religious buildings.
