Porto is full of churches. Some are impressive because of size, style, etc., and others are minimal in every aspects. But almost all have in common being old, very old sometimes ... like this one (although more or less reconstructed).
Something very typical too from Portugal is AZULEJO (meaning ceramic tilework). Azulejos as the ones portrayed have become a typical aspect of Portuguese culture, manifesting without interruption during five centuries the consecutive trends in art.
These azulejos represent Infante Henrique, Duke of Viseu KG (Porto, March 4, 1394–Sagres, November 13, 1460) who was an infante (prince) of the Portuguese House of Aviz and an important figure in the early days of the Portuguese Empire. He is known in English as Prince Henry the Navigator or the Seafarer (Portuguese: o Navegador).
