Sightseeing in London
1.Great Britain’s capital is London, that is why there are a lot of places
of interest there. The best way to get about London and to do sightseeing is of
cause by taxi, but it is very expensive. So, it is more preferable to use the
underground. The easiest way to travel by the underground is to buy an
underground stations map. The word “underground” across the large circle
shows you the stations.
2.From the Tower Hill station it is a short walk to the Tower of London.
It is one of the most interesting places in London. The Tower was a fortress, a
royal residence, a prison and now it is a museum. Not far from the Tower you
can see the Tower Bridge, one of the finest bridges of London.
3.A walk along the Lower Thames Street brings you to the heart of the
City, the historical centre of the capital. There are many famous buildings here,
the Bank of England and St.Paul Cathedral among them. Not far from this
cathedral is Fleet Street. In this area almost all important British newspapers
have their offices.
