OK, so a slag heap may not be everyone’s idea of a holiday attraction, but Ostrava is a city that appeals to people who embrace the gritty things in life.

 The Ema Slag Heap is on the right bank of the Ostravice River and is a real oddity. 

It’s been piled to a height of 315 metres above sea level, but what’s really strange about the heap is that it has a subtropical climate, which sustains some unusual plant life.
