A "love hotel" where you can say a prayer, a reconstituted section of the Senne river at Saint-Géry, an extraordinary private museum devoted to plastic, a farm with sheep, goats, and turkeys at place de l'Yser, Masonic secrets in the Parc de Bruxelles, a hotel overlooking the Grand-Place, a surrealistic trip in a lift, a homage to the military pigeon, potholing at Koekelberg basilica... For those with a keen eye who dare to open doors, Brussels abounds with curiousities and surprising details that will surprise residents as well as travellers who thought they knew the city well.
