Hampshire lies outside the green belt area of restricted development around London, but has good railway and motorway links to the capital, and in common with the rest of the south-east has seen the growth of dormitory towns since the 1960s. Basingstoke, in the northern part of the county, has grown from a country town into a business and financial centre. Aldershot, Portsmouth, and Farnborough have strong military associations with the Army, Royal Navy, and Royal Air Force respectively. The county also includes several market towns: Alresford, Alton, Andover, Bishop's Waltham, Lymington, New Milton, Petersfield, Ringwood, Romsey and Whitchurch.
