Last Updated

Europe has been dealing with record heat waves this summer, and the heat will be here a while longer. The United Kingdom recently recorded its hottest day ever seen, with a temperature reading of just over 104 F° (40 C°). Spain even became the first country to begin a naming system for heatwaves, much like hurricanes. The same heatwave that broke records in the UK was dubbed “Zoe,” which brought temperatures of over 110 F° (43 C°) to Seville, Spain. Some speculate that heat waves will even begin altering the typical European tourist season. As temperatures soar, one of the best places to escape the heat is underground, where temperatures are consistently milder. We’ve compiled a list of six of the best underground European attractions to beat the heat this summer.

Derinkuyu Underground City – Derinkuyu, Turkey

Imagine knocking down a wall in your home and discovering an entire underground city. In 1963, that’s precisely what happened to a man in the Nevşehir Province. After finding a room behind the wall of his home, his curiosity drove him to dig further, where he discovered many tunnels and rooms that formed the underground city of Derinkuyu.

  • Visitors today can enter the city for a fee of 60 Turkish Lira (about $3.35 USD) or opt for a guided tour at a higher cost.

The Real Mary King’s Close – Edinburgh, Scotland

Lying beneath the bustling streets of the Royal Mile are some less crowded, much older streets awaiting. The houses and alleyways have remained virtually untouched since the 17th century, offering a unique glimpse into the past. As the city expanded, Edinburgh wanted to build a Royal Exchange, and decided to build where Mary King’s close sat.

Rather than knock down all the buildings already there, they removed the top floors and used the lower ones as foundations for the new Royal Exchange. Now, visitors can tour these historic streets and buildings and enjoy costumed tour guides who play the roles of historical residents of the Close.

  • Adult tickets are £19.50 ($23.50 USD), and child tickets are £12.95 ($15.60 USD).

The Basilica Cistern Museum – Istanbul, Turkey
