Slovenian studio Korpnik Produkcija has completed a concrete observation tower overlooking the spa town of Rogaška Slatina, topped by an angular glass cafe resembling a crystal.
Designed by Celje-based Korpnik Produkcija with structural engineers Ponting, Kristal Observation Tower stands 106 metres tall and is currently the tallest building in Slovenia.
The studio said it is intended to be a "respectful" meeting point between the town's historic 19th-century spa complex and its more modern centre, where it is positioned.
