Anuradhapura
Located in the north-west of the island, Anuradhapura was the capital of Sri Lanka for 1400 Years. It is slightly more than 200KM from Colombo and a drive of around 6 hours Anuradhapura gained much greater prominence with the advent of Buddhism on the island, after which many significant buildings and monasteries were constructed.
It is called the brazen palace because its roof was once covered with sheets of bronze tiles. A total of 1,600 stone pillars supported the structure. Most of which can still be seen even today.
