Mardan is a city in Khyber Pakhtunkhwa province, about 70 kilometres northeast of Peshawar on the Peshawar-Swat road. It is the second-largest city in the province after Peshawar and serves as a commercial hub for the surrounding agricultural plain.
The main reason a traveller might stop here is Takht-i-Bahi, a UNESCO World Heritage Site about 15 kilometres northwest of the city. The ruins sit dramatically on a hilltop and date from the 1st century CE, making them one of the best-preserved Buddhist monastic complexes in the Gandhara region. The site gives sweeping views over the plain and is well worth a detour if you are travelling between Peshawar and the Swat Valley.
