It's four years since the council promised to spend £2 million upgrading the adventure playground which first opened in 1971.
The new building at the corner of Southwark Bridge Road and Lant Street rises two and and a half storeys as the first floor now offers two climbing walls.
There are three main areas of outdoor space around the building, including a brand new public playground that incorporates a new adventurous climbing structure, swings and slides, a secure central area, which features space for children to grow their own plants and herbs and a new specially designed adventure playground, featuring a central tower with a slide, aerial walkways and numerous Tarzan swings.
"I want to thank people for their help in bringing this playground about and their patience while the work was being completed," said Cllr Rebecca Lury, cabinet member for culture, leisure, equalities and communities.
"The opening of this exciting new facility contributes to the council's commitment to make sure that people in every area of the borough have access to a top quality children's play area.
"I am delighted to be here to open this remarkable new play facility, just in time for the summer holidays, when I am sure it will bring local children much joy."
