Heraklion is the island’s capital and largest city. Its long history began in post-Minoan times, and saw the succeeding of various conquerors, whose traces are still evident in the city. For instance, one of Heraklion's most important landmarks is the Kouless Fortress in the Venetian harbour. In recent years, many streets around the centre have become pedestrianised and link the major monuments of the city, so that one can go about on foot more easily, free from the rush of traffic.

Transport yourself back in time by the ruins of what once served as the most important religious centre for indigenous people on the Peruvian coast. Situated 40 km southeast of Lima, the archaeological site of Pachacamac is a good day trip from the city where you get to explore the remains of pyramidal temples as well as other impressive ancient constructions.

The third largest city on Crete, Rethymno came to life during the Venetian era and is home to many historic buildings, notably hilltop Rethymno's Fortress, which dominates the city's skyline. In the Old Town, Venetian architectural elements coexist with Ottoman ones, creating a unique charm. During spring, the Rethymno Carnival takes place, which is a century-old celebration that has become an institution famous throughout the country.

Just outside Bilbao, in Biscay, the Vizcaya Bridge (Puente Bizkaia) — also called Puente Colgante or the Hanging Bridge — is the world’s oldest transporter bridge, completed in 1893. It connects Portugalete and Las Arenas (Getxo) across the Nervión River and was declared a UNESCO World Heritage Site in 2006. You can cross either by the gondola, which carries vehicles and passengers in about 90 seconds, or on the pedestrian walkway, accessed via lifts in the towers. The bridge stands 45 m high and 160 m long, and its iron-and-steel design was a milestone of industrial-age engineering.
