Fashion designer Vivienne Tam has joined internationally feted architect Zaha Hadid, and mainland and local artists to create artworks for the city's first permanent 'outdoor gallery'. The public square at Sha Tin Town Plaza features 19 pieces - sculptures, furniture, inscriptions of poetry and conceptual works - spread across more than 17,600 square metres. Hong Kong-raised Tam, who returned to the city for the unveiling ceremony on Monday night, designed a 150-metre-long mosaic path based on Chinese peonies, which sits in a quiet corner of the square. 'This is my first try in creating a landscape piece,' Tam said. 'Chinese peony is my favourite flower, and I use a lot of peony patterns in my designs. I hope my piece will give people a sense of fashion when they walk on it.' Barrie Ho Chow-lai, the art square's chief curator and whose Red Box is on display at the square, hoped the project would become a cultural landmark and inspire people to get involved in art. 'With an art square like this, we can show people that art is something you can see, you can touch, and sometimes you can sit on,' he said. 'I do believe that public art has great potential to develop in Hong Kong. It's not necessarily in a square, but can also be on rooftops or under footbridges.' In front of the square's marriage registry office, a pair of giant engagement rings designed by American modern artist Dennis Oppenheim, welcome new couples. A streamlined seating area created by Hadid, winner of the 2004 Pritzker Prize - the world's top architectural award - offers a resting place on the other side of the square. Some of the artworks feature Olympic-inspired elements. Hong Kong artist Danny Lee designed a giant steel Beijing Olympics logo, Dancing Beijing, while Chinese conceptual artist Xu Bing created an installation, Horse Keeps Running. Other featured artists include UK-based Wolfgang Kaeppner and Germany's Tom Thiel. Local artists and architectural designers include Sara Tse, Mok Yat-san and Man Fung-yee from artists' collective Fotanian and Chinese University, and James Law. City Art Square is a joint project by the Leisure and Cultural Services Department and Sun Hung Kai Properties Charitable Fund.
