The Holy Angel Bridge, also known as St. Peter's Bridge, is an ancient Roman bridge that spans the Tiber River and was built in 134 AD by the Roman emperor Hadrian, connecting the city centre with the Castle of the Holy Angel. The bridge is paved with marble and has three bridge arches for pedestrians only. It can be said that it is a very beautiful bridge in the city of Rome. There are twelve vivid angel statues on the bridge. Each angel holds the same torture instrument as Jesus. It can be said that it is a very beautiful bridge in the city of Rome. There are twelve vivid angel statues on the bridge. Each angel holds the same torture instrument as Jesus. The sculptures of two of the angels from the famous Italian sculptor and architect Bernini have been collected in the Santa Adrea delle Fratte church, and two replicas were placed on the bridge. I didn't board the watch because of the time. It was originally a family cemetery built by Emperor Hadrian, first as a fortress to prevent the invasion of the Visigoths and East Goths, then as a prison, and finally into a magnificent papal palace. There are many different kinds of locks on the pier, which represent the wishes of tourists all over the world. Now as a museum, it is said that in 590 AD, Pope Gregory saw the angel over the fort, and later named it St. Angel's Fort.
