>Slovenia, tucked between the Alps and the Adriatic Sea, is a small country with a strong sense of identity and an impressive variety of landscapes. Its capital, Ljubljana, is known for its walkable center and mix of Baroque, Secessionist, and modern architecture. The Ljubljanica River runs through the city and is lined with open-air cafés and artisan shops.

Wales is a country where centuries-old castles rise above green valleys and coastlines are marked by rugged cliffs and quiet coves. Its capital, Cardiff, combines modern architecture with historical landmarks like Cardiff Castle, which has Roman origins and a Victorian Gothic interior.

Tonga is distinctly different to its neighboring island nations. This Polynesian kingdom, made up of 170 islands, carries a proud history that dates back over 3,000 years.

Royal tombs in Lapaha offer a glimpse into the lineage of Tonga’s kings, while village life remains guided by customs that have changed little over centuries.
