The best thing about travel is that it always surprises you. No matter which destination you travel to, you are always bound to be rewarded by beauty in some form or the other. And it is this beauty and the craving for those surprises lingering in the unknown, which makes travel so irresistible and fulfilling. Stockholm, the capital of Sweden, is one such place, where the experiences never end, and neither do the surprises. What left me the most awestruck about this city is the unbelievably gorgeous Stockholm Metro – referred to as the “world’s longest art gallery”! Underneath Stockholm, breathes a labyrinthine network of metro rail lines, criss-crossing across the length and breadth of the city. These are nearly a 100 metro stations, covering a 110km tunnel system. Out of these 100 metro stations, more than 90 are bedecked with massive mosaics, sculptures, paintings, and installations. Since the 1950s, over 150 artists have played a key role in revamping these stations with their magic. The result – the world’s most beautiful metro stations!! T-Centralen is the main hub of the Stockholm Metro, and welcomes its visitors with calming blue shades paired up with minimalistic desgins of leaves and flowers. While touring these art masterpieces (which basically feels like touring an art exhibition – the only difference being, you’re touring on a train, rather than on your feet!), I remember feeling like I had entered the sets of some sci-fi movie, or maybe I was just hallucinating. That’s how I spent my entire day – marvelling at these subway stations covered in art. The more you see these stations, the more you understand the kind of power art has – to transform something so mundane and boring-looking, into something so purely beautiful! Traveling to Stockholm and not taking a tour of the Stockholm Metro, would be a huge mistake! Under no circumstances would you want to miss it. Hope these pictures stand testament to how unique and extraordinary this whole concept of Stockholm’s Metro art is, and that none of the above hype is exaggerated! Stadion is possibly my favourite of all Stockholm metros. The rainbow arch here is simply magical, to say the least! This station is just a few stops away from T-Centralen, and is a sheer treat to capture. The artist decided to cover Solna Centrum in mesmerizing hues of green and red. Over time, more interesting elements were added, including houses, trees, rivers, and rolling green hills. Read More: Stunning Pictures of Sweden! Glittering gold mosaics, paintings of birds, and brick orange walls make Rinkeby yet another classic gem of the Stockholm Metro. Travel back in time with Rinkeby's other artworks that include a massive, golden prehistoric sun and other fascinating mythology based mosaics. Tensta Station was an absolute delight to explore with its vibrant exhibits of animal sculptures and leaves against a bright white wall. Most of these artworks are dedicated to immigrants that have come and settled in Tensta over the years. While most stations had painting and mosaics, Bagarmossen stood out with stunning light panels on each side, with every conceivable shade of colour! I've never ever seen a station more classier than this one! Read More: A Pictorial Journey Through Norway! Kungsträdgården, which means "King's Garden", was home to the regal Makalös Palace, and a beautiful French garden, between the 1600-1800s. The metro art of this station speaks volumes about the history and architecture of Kungsträdgården - all beautifully coordinated in beautiful shades of white, green, and red.
