From a fire-breathing robot dragon to an aerial duet with an urban astronaut - an array of weird and wonderful acts will be entertaining the crowds in Norwich's Chapelfield Gardens this weekend.

The city park is once again hosting the Norfolk and Norwich Festival's traditional garden party, and there is a packed programme of free events for everyone to enjoy.

'For two days we are taking over Chapelfield Gardens and turning it into a place of extraordinary fun for all ages,' said Chloe Hobbs, communications officer at the festival.

'This year we have got a really lovely range of arts performance and dance - and a big mechanical dragon!

Come down and see some art for free. It's the place to be in the middle weekend of the festival, there's so much going on - wonderful art, wonderful food and just lots of really good fun!'

The Garden Party acts include everything from Paka's Elsie Dragon to Les Enfants Terribles' The Fantastical Flying Exploratory Laboratory to Corey Baker Dance's Phone Box show.

Aurora Orchestra will also be popping into Chapelfield Gardens on Sunday afternoon to perform excerpts from Beethoven before heading off on musical a tour of the city, and the quirky Dennis Design Centre will be continuing to create a unique installation for Norwich in the park.

On Saturday and Sunday evening Chapelfield Gardens will be turned into an open-air cinema for Pedal-Powered Car Chase.

Meanwhile elsewhere in the city this weekend Tilted Production and local performers will be presenting the site-specific show Belonging(s) in the Magdalen Street area, The Voice Project will be animating the Colegate and St George's Street area with song, and the Public Jukebox will taking its eclectic mix of tracks to Future Radio, in Mount Road.
