Introduction to the Presidential Palace: The Presidential Palace is located in the corner of Phoenix Park. It is a white western-style building. There is a bright light beside the second-floor window. This light has never been extinguished from 1990 to the present. I heard that during the Potato Famine, a large number of Irish people immigrated to the United States and other countries. In order to bring back the "Irish wanderers in foreign lands", former Irish President Mary Robinson lit a lamp by the window of her office, hoping to illuminate the wanderers. The way home.
