The park surrounds a Jacobean mansion, Holland House, named after its second owner, the Earl of Holland, whose wife was the first person in England to successfully grow dahlias. In the 19th century, Holland House became a hub of political and literary activity, visited by Disraeli and Lord Byron amongst others, but was largely destroyed by bombs during WWII. These days, dahlias are still grown within the 55 acres of Holland Park, which also houses the Japanese-style Kyoto Gardens with its koi carp and bridge at the foot of a waterfall.
