An exhibition on the progress of a new museum at the site of Lei Yue Mun Fort in Shau Kei Wan is being held at the Hong Kong Cultural Centre. The exhibition, Defending the Seaboard - A Preview of the Hong Kong Museum of Coastal Defence, was opened by the Secretary for Works Kwong Hong-sang. Mr Kwong said construction of the museum - to be opened by the end of next year - was no easy task. 'While it is necessary to preserve the invaluable historical relics, it is also essential to make appropriate alterations and provide additional facilities to meet modern architectural standards,' he said. Also speaking at the ceremony, the chairman of the Provisional Urban Council's Museums Select Committee, Mok Ying-fan, agreed it was a demanding task as the site was very rugged. 'There are many complicated technical and architectural problems to tackle, such as geotechnical structures, electrical installations, preservation of the historical remains and natural environment,' Mr Mok said. Organised by the Architectural Services Department and the council, the exhibition comprises 24 panels featuring historical and architectural aspects of the museum. The panels cover the history and changes in Hong Kong's coastal defences in the past 600 years and important military features. In addition, two architectural models and a number of historical relics are on display. One of the models gives an overall aerial view of the museum, including the entrance block, the service block and the cafe block, with 16 preserved military features forming the historical trail. About 30 pieces of historical relics including invaluable items such as an opium pipe, a lamp and a cannon of the early Qing period are also displayed. Visitors can also enjoy a three-dimensional video show. The exhibition, which is the first of its kind to feature the history of Hong Kong's coastal defence, is open at the foyer of the cultural centre until May 24. Admission is free.
