"Tree Branches, Spider and an Incredible Building Because of its unusual tree branches frame, the massive halls and its gigantic whimsical spider, The Qatar National Convention Center is a worthwhile place visiting in Qatar. Not only does it have unique, if not playful, architectural features, but it also is the largest exhibition center in the Middle East with capacity to hold up to 7000 people in its three main halls. From the outside all you see is it’s overhanging roof supported by two intertwined tree-like columns. The gigantic branches are a monument to the Sidra tree of great significance in the Islamic faith. And if the massive trees don’t capture your attention, the colossal spider in the lobby will. A 30ft high and 33ft wide bronze cast of a spider dominates the space. You can walk under the insect and take pictures from every possible angle. At night, the center is lit with a blue light that makes the black spider all the more striking."
