The National Heritage Board (NHB) has launched a documentation project of four lookout towers in Singapore built in the 1960s and 1970s.
The research effort aims to promote greater public awareness of the architectural and historical significance of observation decks, as part of NHB's interest in expanding its database on Singapore's built heritage.
The four are the Seletar Lookout Tower, the Chinese Garden Pagoda, Toa Payoh Town Gardens Lookout Tower and the Jurong Hill Tower.
"We want to raise public awareness among Singaporeans about the architectural and historic significance of these towers even as they enjoy the beautiful views," said Mr Alvin Tan, the board's group director of policy.
The Seletar Lookout Tower, for instance, was officiated by Britain's Princess Alexandra in August 1969 and was designed by the Public Works Department to resemble the shape of a rocket. This reflects the global interest in space exploration at that time, said NHB.
