The Cathedral of the Holy Cross and Santa Eulàlia, or simply the Barcelona Cathedral, is the Gothic cathedral and seat of the Archbishop of Barcelona. Its construction began in 1298 on the site of an ancient Roman temple and took more than 150 years to be completed. Located in the centre of the historic Gothic Quarter of Barcelona, the cathedral is dedicated to the martyr Santa Eulàlia – the patron saint of Barcelona – who was tortured to death in late Roman times. Her corpse is buried under the main altar. Be sure to climb to the roof for a nice view of the city, and don't forget to visit the serene and beautiful courtyard, which is occupied by thirteen white geese representing the years of Saint Eulalia's life before she was martyred.

If you happen to stroll through the many alleys in town, you might stumble upon the Odeon. Only a few steps away from the main road, this Roman theatre was discovered in 1892 underneath buildings constructed upon it over the years. Its remains stand out from the rest of the city, a testament to the long gone Ancient Roman Era.

The world-famous Ice Hotel is located in Jukkasjärvi, 17 km from Kiruna. The world’s largest hotel of its kind, made out of thousands of tonnes of snow and ice, is rebuilt every winter. You’ll be nice and cool as you sleep after a drink in the Icebar, beautifully chiselled out of pure blue ice from the River Torne. Open from mid-December to the end of April. In the summer, you can experience ice art in the hotel’s Art Centre.
