Nepalese Hindu Temple, Burma Lines [????- ]
The temple is marked on the OSM layer of the map above.
I think the temple still exists, as although a large part of the old Burma Lines camp has been re-developed, the modern government map still shows the temple, and positions it just outside the re-developed area.
I'll leave the status as 'unknown' for now, but if anyone visits, please let us know what you find. [Update Apr 2021: As noted in the comments below, the temple still exists.]
