Visit St. Giles Cathedral. The church is the highest Church in Edinburgh. The top of the church is like a crown. It stands beside Royal Mile. St. Gills Cathedral is the main church in Edinburgh and the national church in Scotland. It is said that it was originally built in 1120, then destroyed by fire and rebuilt in 1385. According to the records, St. Gills Church is the power center of the Presbyterian Church of Scotland, which is generally considered as the "Mother Church" of the Presbyterian Church of Scotland all over the world. The history of churches reflects the unique secular and religious life of Scots, as well as the development and evolution of Catholicism in Scotland in the 16th century. The colored glass in Fig. 5 is gorgeous and colorful. The unicorn on the chair (Figure 8) is emblematic of power and carved vividly. Figure 9 shows an angel sculpture outside the church. I highly recommend it.
