The Garden Museum has launched an appeal to raise £50,000 to enable the tower of the former church of St Mary-at-Lambeth to be opened to the public.
As part of the works, there is the opportunity to install a steel platform at the top of the church tower to enable the public to enjoy the spectacular view across the river to the Palace of Westminster.
Wenceslaus Hollar is thought to have stood on top of the tower to draw part of his 1647 'Prospect of London and Westminster'.
The cost of making and installing the steel viewing platform is around £50,000 and the only time that the work can be completed is in August this year.
Further details about the appeal are available on the museum website.
