While the demolition crew was taking down the clock tower at the old Star Ferry pier, students were racing against time to sketch the site before it was destroyed. Ten students from St Paul's Co-educational College were participating in a project titled 'In pursuit of Central and Western District' - aimed at arousing an interest in its heritage sites - before watching one disappearing quickly. Form Three student Peony Shek Yik-pui, 14, said she 'felt lost' when the clock tower was taken down. 'I miss the clock tower. It has witnessed the changes in Hong Kong and I cannot understand why it was taken down.' Schoolmate Chan Lok-yiu, 13, also felt the same. 'The clock tower represents the memories of Hong Kong people. When it was taken down, the memories were gone.' She had done a detailed sketch of the clock tower and the demolition crew. Led by local artist Ng Che-lun, the students were among the last people to witness the removal of the clock tower. He said their sketches would help preserve memories of the site. 'I told the students to do a sketch of the clock tower right away. The bell was the most important part of the building and we had to catch the moment before it disappeared,' he said. Ng did a sketch himself before the clock tower was taken down. He said the sketch would be named 'The last moment of history'. Co-organiser Roger Ho Yao-sheng, project manager of The Conservancy Association Centre for Heritage, said they had not planned to do any sketches. He said their project had been planned long before the site was to be demolished, and they were surprised this had taken place so soon. 'I think this experience will have a big impact on the students. They witnessed an historic moment.'
