The country is divided into Highlands and Lowlands. Most of the industry is concentrated in Lowlands, in the Clyde Valley.
Glasgow is its largest and busiest town; Edinburgh is its capital. Glasgow and Edinburgh are two great centres of Scotland. 
Edinburgh is rather cold but attractive. Edinburgh is known as Athens of the North. If you walk around the city you can touch on history at every step. Practically every building has a tale to tell. The two most interesting parts of the city are the Old Town and the New Town. The Old Town lies between the Castle and Holyrood Palace. The Castle, in fact, is older than the city.
One of the most modest and yet one of the best known monuments in Edinburgh is a monument to dog called Bobby. The dog belonged to John Gray. When he died Bobby lived near his grave for twenty-six years. Later Bobby was buried near his master and his statue in the Old Town has become a symbol of devotion.
The Old Town is a striking contrast to New Town with its white and beautiful streets. Princes Street is the most beautiful street of the New Town. It is Edinburgh’s popular shopping centre. Princess Street lies between the New Town and the Old Town. The modern town is on the lower side, the old one – on the higher. They look at each other across the valley under Scotland’s blue sky.
