波爾圖主教座堂（Sé do Porto）見證葡萄牙王國的誕生與演變

波爾圖主教座堂（Sé do Porto）見證葡萄牙王國的誕生與演變 始建於1110年，古樸羅曼式教堂，那時葡萄牙還是萊昂王國的附庸。 1147年首任國王阿方索·亨里克（Dom Afonso Henriques）在攻占里斯本前夕，選擇在此舉行重要軍事會議，教堂隨之成為新興王國的象徵。 1387年，葡萄牙國王若昂一世（João I）與英國蘭開斯特的菲利帕在此成婚，簽訂了著名的“溫莎條約”（英葡同盟），該條約至今仍然有效，是世界上最持久的外交同盟。 1736年建築師尼古拉·納索尼（Nicolau Nasoni）為其增設了華麗的巴洛克門廊和側翼迴廊，將內部裝飾得金碧輝煌，但哥德式的玫瑰窗與堅固的塔樓仍被保留下來。 Porto Cathedral (Sé do Porto) witnessed the birth and evolution of the Kingdom of Portugal. Founded in 1110, this ancient Romanesque church dates back to when Portugal was a vassal state of the Kingdom of León. In 1147, the first King, Dom Afonso Henriques, chose this cathedral to hold an important military conference on the eve of his conquest of Lisbon, thus making the cathedral a symbol of the emerging kingdom. In 1387, King João I of Portugal married Philippa of Lancaster in England here, signing the famous Treaty of Windsor (the Anglo-Portuguese alliance), which remains in effect today and is one of the world's longest-lasting diplomatic alliances. In 1736, the architect Nicolau Nasoni added a magnificent Baroque portico and side cloisters, adorning the interior with gold, but the Gothic rose windows and sturdy towers have been preserved.
