I participated in a heritage walk on my city Dehradun. We went to a old heritage building of the city known as Guru Ram Rai Darbar. It is considered to be the place from where foundation of Dehradun started. While roaming around building I discovered this wooden wall clock. It seemed to be very old and rare. The most amazing thing i found about it was that it not only shows time but date too which I have never witnessed nor ever heard of.
