Guided by Google Maps on the iPad, we soon arrived at the Circle Square. This square has its own characteristics, with towering trees in the middle and round buildings around it. Although it is monotonous, its architectural layout is unique. It is said that the designer designed the building based on the sun, while the Moon Tower located not far away is the designer's son's masterpiece. It is said that it is a half-crescent building based on the moon. The two generations of father and son shine together, leaving a model of human architectural design, but also for this ancient city to add elements of modern architecture. We stood in front of the Crescent Tower for a long time. This building, composed of 30 connected buildings, contains 114 columns. The roads and houses are arranged in a delicate crescent arc. It is the first time that we have seen such a large building with such beautiful curves. It is indeed a full display of a graceful noble elegance. It is reported that part of the Crescent Tower has been transformed into the Royal Crescent Hotel, which is one of the top star hotels in the area. And this 18th century building is also known as the best of contemporary architecture, because it almost perfectly combines the British aesthetic orientation and Italian style of gorgeous architecture.
