Located in the heart of Strasbourg, the Strasbourg Cathedral, completed in 263 years, is one of the most important historical buildings in the Middle Ages and a famous Gothic church in Europe. The church is entirely made of pink sandstone from the Vosges Mountains. On the top of the front, on one side is a 142-meter-high minaret, but on the other side there is only one platform. It should have been a symmetrical spire. It was not built because of the limited financial resources at that time. Now it has become its characteristic. The Fortress Cathedral is also very famous. Ascend to the top of the tower, the city's beautiful scenery and magnificent forests and mountains are unobstructed. There is an 11-meter-high astronomical clock in the church. Every 15 minutes, there are children, young people, young people and old people who represent the four stages of life. But every hour, there is a god of death. The timekeeping time is accurate, and by the time the clock is heard at 12:30, there will be a lot of characters coming out of the field, bringing a compelling, lively and humorous scene.
