The picturesque medieval town of Kutna Hora, around 70 kilometres east of Prague, was once one of the largest towns in Europe, and was a centre of copper and silver mining. Nowadays, it is extremely popular with tourists, and one of the latest attractions in the town is a museum of alchemy. I recently visited the alchemy museum, which is located in the perfect setting of the Sankturnin Palace, on Kutna Hora's main square.
