The largest cathedral in Bosnia and Herzegovina, the Sacred Heart Cathedral in Sarajevo also happens to be one of its most photogenic. Of course, churches aren’t built with Instagram in mind, but this 19th century beauty was constructed by people with an eye for style. A Neo-Gothic stunner with plenty of Romanesque touches to keep you guessing, the cathedral is as beautiful inside as out, with jaw-dropping colour and intricate design vying for the visitor’s attention. The cathedral is in the centre of town, you can’t really miss it, and you will 100% take a photo of it.
