Circuses travelling across Europe are obliged to comply with a vast number of technical requirements, regulations and restrictions. Until today these requirements differ from country to country and sometimes even within one country. For example, the signs pointing to emergency exits must be green in one country, red in another. Aisles must be 1 meter in one country, 1.20 meter in another. Such different regulations prevent the circuses from exploiting their right to move freely within the European Union. ECA has worked in Brussels on the standardization of these technical regulations and will continue to do so until circuses can move freely from country to country and entertain their audiences wherever they are in Europe.
