Edinburgh effortlessly balances its weighty history with contemporary energy. The Royal Mile’s weathered cobbles lead past medieval closes and modern whisky bars, while the shopfronts of Princes Street mirror the jagged skyline of the Old Town. By day, you can hike up Arthur’s Seat for panoramas that stretch to the Firth of Forth; by evening, join the animated crowds at the Edinburgh Festival Fringe or browse the shelves of independent bookshops. Scotland's compact, hilly capital is a city where every alley holds a story waiting to be uncovered.

A gateway between the two nations of the Iberian peninsula, Badajoz lies as close to Lisbon as it does to Madrid or Seville, and the city draws on influences from both sides of the border, as well as from centuries of tumultuous history, to form its distinctive character. Winding medieval alleys and a skyline dotted with palace towers make the historic town a sight to behold, while the remnants of the majestic Alcazaba watch over the city as they have for centuries, once an impenetrable fortress that protected the area from countless invasions.

Limerick, located on the banks of the River Shannon, holds the distinction of being Ireland's first-ever City of Culture.

Known for its strong rugby culture, Limerick also has a thriving street art community, a bustling festival calendar, and the Milk Market that serves as a hub for food lovers.

"The city in its setting and entire surroundings may be said to have something ideal." (Johann Wolfgang von Goethe, 1797). Scarcely any other European city has had its praises so often sung as Heidelberg. The mysterious Heidelberg Castle, the picturesque Old Town, and as Goethe himself stated, the perfection of its setting – in the nineteenth century, all of this attracted the German romanticists, who immortalized Heidelberg in poetry, music, and art. Today the charm of Old Heidelberg is combined with a future-oriented and international focus.
