Temple of 500 Buddhas

I don't recall the name of this monastery we passed on the drive from Anaradhapura to Tanthirimale. They are constructing a unique pathway lined with about 500 statues of the Buddha. I guess it will be a reflection walkway instead of designed for meditation because it ultimately leads up to some kind of temple building too early in construction to be identified. Well, I guess the modern attempts at devotional expression deserve some honorable mention.
