Austrian, German and international celebrities, including the famous Beyoncé, head to this one-of-a-kind store to buy stunning sunglasses or international eyeglasses. This place was founded in the late 1970s by ophthalmologist Peter Kozich, who makes frames from natural materials including buffalo horn, gold, platinum and various woods in his 13th century Austrian country house. In addition, designs can be made to order, it is an amazing store and well worth a visit.
