No way dude, its dharahara, not twin tower. There is no elevator or light bulb. If you have not been in there its better u go there. Every one will appriciate its engeneering and construction. There are 355 stairs to climb it. You can see whole kathmandu from there. You get nice view of the valley dude. I really appriciate the engeneering and construction of the tower, considering the fact that it was made 100s of years ago. I am not sure about the date. You won't feel that you have already climbed that hight. Its just awesome. I really loved it. This is the second time they have opened it for public ( as far as I know). Try to appriciate the intellect of nepalese bro. Jai Nepal
