Some media channels are projecting as if World Heritage Sites of Nepal and all historic architecture are destroyed by the recent earthquake. This is not true. 
Hanuman Dhoka is severely destroyed. This has not affected the house where Kumari (the only living goddess) lives. Dharahara (symbolic tower) have been completely devastated. Dharhara is not UNESCO declared World Heritage Sites of Nepal. It was a historic monument open for all.

Please note: Patan, Bhaktapur, Pashupatinath, Boudhanath and Swayambhu have not been damaged much. Old palaces in Patan and Bhaktapur are fully intact. The tallest temple of Bhaktapur (5-storyed temple) stands strong. Holding high its centuries old heritage.

Nepal tourism after earthquake has been hit hard. More than 75% of the tourist arrivals are cancelled. Hotel bookings are cancelled. This is due to the wrong over escalated news by the media. Both domestic as well as foreign media falls under this. They only highlight the damaged buildings and roads.

There is plenty to see in Kathmandu and beyond. As truly said by Nepal promotion tag line “Once is not enough”, “nothing is enough to end tourism in Nepal”. Nepal tourism after earthquake has stood firm. Tourists have a lot to see in Kathmandu. Roads connecting to and from Kathmandu have no problem.
