Isn't it wonderful walking here ?   What do you mean ?   I mean look at all these magnificent buildings around us .   Yes , look over there . That's the Empire State Building . My book says it's 102 stories tall .   It's quite famous but don't you think it looks a bit old-fashioned ?   You're right , but when it was built in 1930 it was a marvel of technology and engineering .   What other important buildings are we going to see on Fifth Avenue ?   Quite a number . Actually every skyscraper has a history . A few blocks ahead we'll see St.Patrick ' s Cathedral and just across the street will be the world-renowed Rockefeller Center . It's a landmark in the history of architecture .   What's there after that ?   Well then , there's a Central Park . Facing the park on Fifth Avenue is probably some of the most expensive properties in the world .
