dear alex,

 

how are you? i am in the capital of england — in london. my parents and i always dreamt about seeing this nice city.

 

there are a lot of beautiful old buildings. we have alredy seen westminster abbey, big ben (now it called elizabeth’s tower), the houses of parliament, buckingham palace, st. paul’s cathedral, london bridge, the tower of london and the waxworks madame tussaunds museum. there are the models of famous people from pop stars to prime ministers made from wax in this museum. they look like real. it’s so interesting.

 

my parents and i are walking on trafalgar square now. there is nelson’s column in its centre which is guarded by four lion statues at its base. by the way, i sent you this postcard with a picture of trafalgar square.

 

the weather is not fine today, it’s foggy and rainy. but it doesn’t spoil our walking.

 

we took much photos. next week we will be at home and i’ll show you them.

 

don’t miss the chance to visit england and london.

 

best wishes,

maria
