To celebrate all the floral motifs that distinguish and beautify the landscape of the city and the municipality, the Viana do Castelo City Council holds an event every year in May that involves different experiences exalting flowers, gardens and green spaces. During this initiative, thousands of natural flowers give a new colour to the city, through the participation of various professionals of the floral art, in a lively and pleasant atmosphere.

Let us remember that Viana do Castelo has three major festivals around flowers: Festa das Rosas, in Vila Franca; Fiestas de Santa Cruz, in Alvarães; and Romaria N.ª Sr.ª Encarnação, in Vila Mou.
