Not to be confused with Westminster Abbey further down the road,
Westminster Cathedral is the main Catholic church of England and Wales.
As churches go, it's not that old - the foundation stone was put down in 1895. Construction was completed eight years later in 1903.
While the design of its exterior, built in a Byzantine style, may not be to everyone's taste, step inside its doors and the noise and pace of London melts away, leaving you staring at something so grand you'll wonder why you hadn't visited sooner.
Wander slowly through the cathedral and enjoy its peaceful ambience or simply take a seat and soak it all up from there.
For those interested, there's the
Treasures of Westminster Cathedral exhibition. Costing £5 (concessions £2.50), you can see a variety of rare ecclesiastical objects, ornate chalices, and so on, and find out how the cathedral was created.
Treasures of Westminster Cathedral is open from 9.30am to 5pm Monday to Friday, and from 9.30am to 6pm on the weekend.
One thing you won't want to miss is the view from the top of its tower. The
Tower Viewing Gallery offers impressive views across the capital from a height of 64 metres (210 feet).
Westminster Cathedral holds a number of events throughout the year, which you might want to attend - click

The cathedral is situated in the kind of location where you don't really need to make a special plan to visit - you'll stumble across it sooner or later.
It's very close to Victoria station, and whether you live in the capital or are visiting as a tourist, who doesn't go through Victoria station once in a while?
Overground trains, underground trains, buses and coaches all converge on this busy part of London - all you need to do is walk five minutes along Victoria Street and you'll see Westminster Cathedral on your right.
