Cardiff is known for its extensive parks and other green spaces covering around 10% of the city's total area. Cardiff's main park, Bute Park (which was formerly the castle grounds) extends northwards from the top of one of Cardiff's main shopping street (Queen Street); when combined with the adjacent Llandaff Fields and Pontcanna Fields to the north west it produces a massive open space skirting the River Taff. Other popular parks include Roath Park in the north, donated to the city by the 3rd Marquess of Bute in 1887 and which includes a very popular boating lake; Victoria Park, Cardiff's first official park; and Thompson's Park, formerly home to an aviary removed in the 1970s. Wild open spaces include Howardian Local Nature Reserve, of the lower Rhymney valley in Penylan noted for its Orchids, and Forest Farm Country Park, over along the river Taff in Whitchurch.
