There were unexpected storms and clouds, and the sun was bright in the morning. By noon the sun hid in the clouds, and the sky suddenly clouded down. After lunch as planned, we will go to the third stop "Carlsberg Tourist Center", which is located in the suburbs of Colombia and has a long way to go. After consulting the owner of the cafeteria about the bus route, he walked in the direction of the guide to the subway station. On the way, I did not expect to pass by the famous scenic spot "Round Tower" and hold Copenhagen Card is also a free scenic spot, which can not be missed by chance. The circular tower was built in 1642 with a diameter of 15 meters and a height of 36 meters. Originally a subsidiary building of Trinity Church, it provides astronomical observatory and library functions for scholars. Now it is a scenic spot for tourists. The turning ramp in the inner circle overlooks the panoramic view from the top.
