I met Nuwan in Colombo, Sri Lanka back in 2011. Not long ago, he shared fascinating images from a trip he made to historical Polonnaruwa. I posted several below. You can also spot Nuwan in the next to last image.
Ancient City of Polonnaruwa
Polonnaruwa was the second capital of Sri Lanka
after the destruction of Anuradhapura in 993. It comprises, besides the
Brahmanic monuments built by the Cholas, the monumental ruins of the
fabulous garden-city created by Parakramabahu I in the 12th century. - UNESCO World Heritage Site
