Known for its unique Art Nouveau architecture, Helsinki seamlessly blends historic charm with modern innovation, and is a vibrant hub of culture and design, home to numerous museums, galleries and theatres. A two-night break will set you back at least £587 ($753) but comes with the chance to visit the iconic Temppeliaukio Church, carved directly into solid rock, or the striking Helsinki Cathedral overlooking Senate Square. Warm up with a traditional Finnish sauna experience, an integral part of local culture, and indulge in hearty Finnish cuisine at cosy, candle-lit restaurants – if you have £117 ($150) for a three-course meal, that is.
