Visit Gibraltar

Visit Monaco, the second-smallest sovereign state in the world. Explore the Prince's Palace (official residence of the Grimaldi family with daily changing of the guard), try your luck at the Casino de Monte-Carlo (iconic Belle Époque building featured in James Bond films), and stroll through the Jardin Exotique (botanical garden perched on cliffs with over 1,000 succulent plants).

The world's smallest state holds its biggest art: St Peter's, the Vatican Museums and the Sistine ceiling

Visit Luxembourg, a small landlocked country in Western Europe. Explore the UNESCO-listed Old Town of Luxembourg City with its fortifications and casemates, see the Grand Ducal Palace (official residence of the Grand Duke), walk across the Pont Adolphe (a stone arch bridge offering views of the Pétrusse Valley), and try local dishes like judd mat gaardebounen (smoked pork with broad beans) or gromperekichelcher (potato fritters).

Visit San Marino, the world's oldest republic founded in 301 AD. Explore the historic center of San Marino City, a UNESCO World Heritage site with medieval fortifications like the Three Towers (Guaita, Cesta, and Montale) offering panoramic views of the Italian countryside. See the Palazzo Pubblico (government building with Gothic architecture) and the Basilica di San Marino (neoclassical church housing relics of Saint Marinus).
