一九四九年,为迎接开国大典,重点对天安门城楼多年来积存的鸽粪、蒿草等污物,破损的砖瓦、门窗等构件进行了彻底的清理和整修。一九五二年,更换破损的门窗和腐朽的梁木,对屋顶梁枋和天花藻井的彩绘重新进行了彩画,取出了城楼西木梁上三颗未爆炸的八国联军炮弹。一九五六年,对城楼东北翼角及劈裂、脱榫的角梁进行了翻修。 In 1949, in order to welcome the founding ceremony, the focus was on thorough clean-up and refurbishment of debris, wormwood and other contaminants, damaged bricks, doors and windows, and other components that had accumulated over the years in the Tiananmen Gate. In 1952, damaged doors and windows and decaying beams were replaced and colored paintings of roof beams and ceilings were repainted. Three unexploded eight-nation coalition shells on the west wooden beam of the tower were removed. In 1956, the corners of the northeast wing of the tower and the chasm and split corner beams were renovated.
