【明報專訊】OVER the past year many Song and Yuan relics have been unearthed at the site of the future To Kwa Wan station of the Shatin to Central Link (SCL) of the mass transport railway system. They include square wells, stone wall foundations, house foundations and a river branch. The sensational discoveries are regarded as additional and corroborative evidence of Hong Kong history. They are proof that the territory was inhabited as early as the Song Dynasty.
