Some kind of border stone found on Beacon Hill, right next to the road, near the top. On the stone I can find the weathered marking "1902", I assume this is the year. The rest of the markings I could not recognise, and as my friends wanted to move on I did not have time to study it in detail.
I think the stone marks some kind of border, considering the location I think this may be the northern border of Hong Kong.
