St. Serenan's Cathedral is a beautiful and well-preserved cathedral with a long history. Under the blue sky and white clouds there is only a beautiful and solemn feeling. He is open all day. From the Arc de Triomphe bus stop in Barcelona, there is a bus to Toulouse for 28 euros, five hours. Very convenient. Toulouse is beautiful. Shopping is more convenient and friendly than Paris. It's worth going. It's easy to get from there to the south of France.
