Michel Jacques will introduce – to the residents of Le Domaine de la Gracieuse aparthotel in Lonay – two architects who have marked the Baroque art and have greatly contribuated, through their works,  to the beauty of the city of Rome. While Bernini made the colonnades in Vatican’s St-Peter Square, his confrere – Borromini – constructed the San-Carlo-alle-Quattro-Fontane’s Church.
