Top things to do in London, England
"Hyde Park is central London's largest green space, expropriated from the church in 1536 by Henry VIII and turned into a hunting ground and later a venue for duels, executions and horse racing. The 1851 Great Exhibition was held here, and during WWII the park became an enormous potato field. These days, it's a place to stroll and picnic, boat on the Serpentine lake, or to catch a summer concert or outdoor film during the warmer months."
