A "tower of Babylon", symbolizing all languages and cultures.
The tower is changing from an ancient stone tower into the top of a colorful ceramics ornamented torette (Gaudi; photo taken in Barcelona).
The lower part stands for heredity, tradition, respecting and keeping the historical elements of every culture.
The top symbolizes the modern and contemporary "internationalizing" of languages.
The slogan says: "Innovate your language & keep the heredity of all others".
