Segovia Cathedral, the tower needs to be guided by a guide, and individuals cannot go up. Go up the steps in a circle, stop 3 times, you can visit, listen to the guide in Spanish and English. The first time I was sitting and watching the film while resting, the second time I mainly looked at the residence of the bell-ringing people. I heard the introduction that the kitchen said the most important thing, because it was the warmest in winter. There are also natural refrigerators and bedrooms, but in winter, I usually live in the kitchen and the bedroom is too cold. Also visited the house of the clock, it is said that one clock and one house, by pulling the rope to ring the bell. The third time I arrived at the top, there were 10 clocks around, and it would ring at 12 o'clock, so I must go down before 12 o'clock, otherwise my ears could not stand it. It is said that there is another clock on it, which is knocked every 30 minutes, of course, now it is electric. Take a photo in a circle, overlooking the city, the snowy mountains in the distance and the castle nearby.
