description Lake Feneketlen (aka „Bottomless Lake”) is a lake in the 11th district of Budapest.The lake was formed in 1877, when clay was removed from the site to supply a brick factory that was situated at nearby Kosztolányi Dezső tér. The lake’s water quality in the 1980s began to deteriorate, until a water circulation device was built. The lake today is a popular urban place for fishing. location additional info open hours Monday 0:00 - 24:00 Tuesday 0:00 - 24:00 Wednesday 0:00 - 24:00 Thursday 0:00 - 24:00 Friday 0:00 - 24:00 Saturday 0:00 - 24:00 Sunday 0:00 - 24:00 contact Share share on: Share this...FacebookPinterestTwitterLinkedin copy link: Get directions
