Leaving the Sighing Bridge and before the Sheldonian Theatre, there is a row of ancient Roman philosopher statues on the front wall of the building, which is extraordinarily solemn, simple and elegant. Built from 1664 to 1668, this circular building is the traditional venue for the Oxford University Degree Award Ceremony. Thousands of Oxford students graduated from Oxford and went to all over the world, so it is also a place to witness Oxford's achievements. Theatre is also often used to hold public concerts. At that time, the hall seemed to be preparing for the evening concert. An old man was debugging a piano of an antique musical instrument. It has a keyboard for the piano and strings for the harp. Such a mixing structure is rare. The lofty theatre hall has three-storey stands, which are not big enough and have limited capacity. The huge ceiling depicts Christian pictures. It is said that this is a beautiful 17th century painting, reflecting the conquest of truth over ignorance. The main part of our tour in this theatre is to climb the observation deck on the top floor and look at the surrounding campus scenery from afar. There are all kinds of high spires, ancient and solemn buildings, ancient buildings, and people coming and going. Although we can't see the Oxford panorama from the telescope, we are shocked by the local momentum. This is the real Millennium Academy. This is the complete university city. This is the real dream. Combining the cobblestone roads, the adjacent colleges, the different styles of buildings, it's easy to understand why so many students from all over the world come to Oxford during the summer vacation. This is indeed a place of pilgrimage to higher learning institutions. If the conditions really should let students come here to feel for themselves, what they see and hear will definitely leave a deep imprint on the formation of children's world outlook.
