Originally, Barcelona's trip was dedicated to Gaudi, but a small thing led us to change our schedule and come to such a concert hall. On the way to the concert hall, Sari sketched it. It was designed by Louis & Domank. It is the only Concert Hall in Europe that uses natural light. Apart from the super-large stained glass windows on both sides of the stage, the most attractive lighting facility is the huge dome of stained glass, which is inlaid with colorful Angel choirs and geometric figures. Along with the cold tones around it, it gradually moves to the center. The warm tone is excessive, starting from the middle to protrude downwards, forming a natural water drop shape with narrow outside width, as if pushed by sunlight, reflecting the natural light into the hall can illuminate the whole hall. The glass dome is surrounded by golden relief frames and surrounded by large groups of double-color flowers, which weakens the lightness of the glass. You can't imagine if you understand every word. It's more direct to pay for a visit. Although I speak Spanish-style English, it doesn't affect me enjoying at all. It takes about one hour. The lecturer will lead you to visit from bottom to top. First, we will come to Modernist Concert Hall. Here, the audience will watch a 10-minute short film through a projection screen, introducing the design, construction and construction of the Catalonian Concert Hall. Up to completion and so on. In this hour, I just feel that my eyes are really not enough, every detail is too perfect, the lens can not depict her charm and her gorgeousness. The waiting area is actually a coffee bar, which should be specially designed for tourists waiting to visit. After visiting the concert hall, I was surprised to find that the style of this coffee bar and the whole concert hall is completely integrated, although the use is different, but the configuration is the same.
