In the streets of the city, it is easy to see the tall Cathedral of Glasgow in the distance, surrounded by statues of religious figures, behind which is the hillside green space, bathed itself in the rising blue sky and white clouds. The cathedral, which was built in the 6th century A.D., is the only oldest building in Glasgow. It is said that it took more than 300 years to complete the construction of the cathedral. How long will it take? After that, the cathedral has survived the devastation of the religious revolution several times and has been fortunately preserved to this day. Of course, people can still see that the cathedral is damaged to varying degrees everywhere, and even some places can clearly see the ruins and broken walls of that year. We walked into the free and open cathedral, which has been visited by many tourists. The cathedral is also one of the most popular tourist attractions for visitors to Glasgow. The interior of the cathedral is very grand and tall. The arch wall formed by ancient columns extends the roof of the cathedral to high altitude. The wooden roof is inlaid with various national emblems. The walls of the church are surrounded by tombstones and sculptures. Many visitors who have studied religion are watching these tombstones carefully, but we can only see a macroscopic scene. The most different thing from the general cathedral is that the glass windows of the cathedral seem to be quite plain. In the center of the church, the cross-section is divided into two parts by a stone altar fence decorated with seven pairs of stone statues, which is said to symbolize the "seven sins" in Catholic doctrine. We began to refer to the text introduction, looking for a long time did not understand, and then asked the staff to get advice, is to see a bit of fame. There is also a large basement in the church, which also has an arch wall, with a sacred tombstone surrounded by red ropes. The tombstone belongs to St. Mungo, the patron saint of Glasgow. It is said that at the end of the 6th century, this Saint established and named Glasgow here. Of course, it also makes Glasgow Cathedral a witness of the city's history. On the murals behind the tombstones and on the church carpets, guides usually introduce visitors to the four wonders of the church - "birds that can't fly, trees that can't grow, bells that can't ring and fish that can't swim. It seems rare that such a meaningful cathedral is so old.
