Not every skyline is characterized by a high density of towering buildings. Take London, for example. The understated skyline, which has only a few skyscrapers, highlights London's classic charms. Much of the city was constructed before high-rises were in vogue. Nonetheless, London's landmarks match those of Paris in terms of notoriety. Big Ben, the London and Tower bridges, and more modern sites like the London Eye give sightseers plenty to look out for.
A ride on the Eye itself is a great way to get your bearings. The 30-minute ride on the giant Ferris-wheel structure provides a glimpse of many London's landmarks, as well as some great views of the River Thames. People who don't want to spring for the pricey (but worthwhile) ride can climb the Primrose Hill in Regent's Park or Parliament Hill, which sits on the edge of the spacious Hampstead Heath. Both these vantage points offer great views of London's rooftops.
