It follows two years of regeneration work that has seen a refurbishment of the watercourses, renovation to the rockeries and the monuments, as well as the installation of a new play area.

The project also included an extensive planting scheme along with improvements to the paths and bridges.

In the final stages of the project a new boathouse kiosk was built next to the lake and the cafe has been extended to include a community room as well as a ranger base for educational events.

A host of games and activities on offer throughout Saturday, with visitors invited to take a guided tour of the park with the rangers.

Bill Maynard, HLF North West Committee member attended the event, saying: “It is a privilege to be here to see the wonderful work that has been undertaken to restore and revitalise nearly 140 years after the gates first opened. The park is well used and well loved by the local community, and with our support this restoration will ensure this park’s important historic features will be preserved, whilst making sure Sefton Park continues to be safe and enjoyable place for the local community to spend time.”

The £7million restoration began in 2008 and was funded by a £4.7m grant from the Heritage Lottery Fund with Liverpool City Council providing the remainder of the money.

Cllr Tim Moore, Cabinet Member for the Environment, said: “Sefton Park is our biggest and most popular park and it has now been restored to its former glory.”

“As well as new facilities, the spectacular views, which were part of the original vision for the park, have been restored and the lake and watercourses massively improved.”

The restoration was carried out by Birse Civils and other partners including 2020 Liverpool, Anelays Ltd specialist masonry, Glendale Liverpool grounds maintenance, Arup – consultant engineers, LDA Design landscape architects, Lloyd Evans Prichard building conservation architects and Mansell construction company.

The National Museums Liverpool were also involved in the conservation work carried out at the site

The Aviary Café has undergone an extensive makeover, creating an innovative interior and re-planned terrace area, multi-purpose community room and a Park Ranger station looking out to the restored Eros fountain.

The restoration of the café was made possible in part thanks to the hard work of tenant Gino Ferraiolo who worked alongside designer SD interiors (NW) Ltd

The new café and restaurant will both be renamed and "The Panoramic".
