Thuparamaya
King Devanam Piya Tissa built the Thuparama dagaba to enshrine the Right Collar Bone of Lord Buddha. The Thuparama is regarded as the first ever historical stupa built in Sri Lanka. Originally it was in the shape of a heap of paddy but as restorations were done in later years, it took the form as seen today. It has a diameter of 59 feet 6 inches (18.14 m) at the base. As the name suggests, Thuparama comprised a ‘stupa’ and an ‘arama,’ a residential complex. Ruins of such a complex can be seen within an area of over 3 acres (12,000 m2) around the ‘stupa.’
