Europe is facing record heatwaves this summer and the heat will be here for a while longer. The UK recently recorded its hottest day on record, with a temperature reading of just over 104 F° (40 C°). Spain even became the first country to start a naming system for heat waves, like hurricanes. The same record-breaking heatwave in the UK was dubbed ‘Zoe’, which brought temperatures of over 43C to Seville, Spain. Some speculate that heat waves will begin to alter even the typical European tourist season. As the temperatures rise, one of the best places to escape the heat is the basement, where temperatures are consistently milder. We’ve put together 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 house and discovering an entire underground city. In 1963, this is exactly what happened to a man in Nevsehir Province. After finding a room behind the wall of his house, his curiosity prompted him to dig further, where he discovered many tunnels and rooms that formed the underground city of Derinkuyu.

The exact age of the tunnels is unknown, with various experts placing their origin between 1500 and 700 BC.

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

The Real Mary King’s Close – Edinburgh, Scotland

Beneath the busy streets of the Royal Mile are some less busy streets, where much older roads await. The houses and alleys have remained almost untouched since the 17thu century, offering a unique glimpse into the past. As the city expanded, Edinburgh wanted to build a Royal Stock Exchange and decided to build where Mary King’s cronies sat.

Instead of knocking down all the buildings that were 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 playing the roles of the historical residents of Konto.

  • Adult tickets are £19.50 ($23.50 USD) and children’s tickets are £12.95 ($15.60 USD).

The Basilica Cistern Museum – Istanbul, Turkey

  • Admission to this historical wonder costs 190 Turkish Liras (US$10.60) and the Cisterna is open to the public every day between 9 a.m. and 7 p.m.

After taking a train to enter the mine, descend 130 meters (426 feet) below the surface and cruise on a raft across the 100-meter-long, 40-meter-wide Mirror Lake. Dazzling lights highlight the cave’s salt crystals as you pass over the water. Average temperatures at the mine are around 12 C° (45 F°), making it an ideal escape from the summer heat.

  • Adult tickets are €21 ($21.38 USD), while children’s tickets are €10.90 ($11.10 USD).
