Downtown (El Centro) is the actual backbone of Cancún. What it lacks in history, it makes up for being a true melting pot — an exciting mix of the old traditional Mexico and an ultra-modern urban sprawl. Avenida Tulum, the main street, passing through the heart of the city, is easy to reach by public transport. The street is lined with shops, cafés, bars, and restaurants. Be sure to stop by Parque de las Palapas, on the market square, where locals come to chat and watch the entertainment provided by various local groups. The lively atmosphere and the sound of Mexican music are infectious, and any worries will quickly be postponed to "mañana." Browse around the artisan stalls and try some of the local sweet delicacies or visit the "Hippie Market" around the corner. In the evenings, the place to be is Avenida Yaxchillan with its lively restaurants and bars, popular with locals and tourists alike.

The construction of the impressive Saint-Pierre Cathedral began in 1162 under Henry II of England and Eleanor of Aquitaine. Inside, visitors can see a 12th-century window depicting the crucifixion of Christ, his ascension and resurrection, along with other architectural beauties.

Regarded as one of the most beautiful neo-Gothic churches in the Netherlands, the Sint-Willibrordkerk is home to a remarkable collection of art and wood carvings. Contrary to what everyone might expect, the interior of the church is adorned with a giant LED halo, artwork by Titia Ex, part of Utrecht Lumen on the roof. The church also boasts intricate decorations and stunning stained glass windows. To top it all off, the church hosts concerts regularly, given its ideal setup for choir singing.
