Presently, Tartu is also known for several modern buildings of the "steel, concrete and glass" variation, but has managed to retain a mix of old and new buildings in the centre of town. Notable examples include the Tigutorn Tower and the Emajõe Centre, both built during the current period of independence; Tartu's tallest and second tallest towers, respectively. Tartu's large student population means that it has a comparatively thriving nightlife, with many nightclubs, bars, and restaurants, including the world's highest-ceiling pub, in the historic Gunpowder Cellar of Tartu.
