In Chap 3 of The Horse and his Boy can you describe Tashbaan? What happened to Shasta in Tashbaan?

Tashbaan:

A broad river divided itself into two streams and on the island between them stood the city of Tashbaan, one of the wonders of the world. Round the very edge of the island, so that the water lapped against the stone, ran high walls strengthened with so many towers that he soon gave up trying to count them. Inside the walls the island rose in a hill and every bit of that hill, up to the Tisroc's palace and the great temple of Tash at the top, was completely covered with buildings—terrace above terrace, street above street, zigzag roads or huge flights of steps bordered with orange trees and lemon trees, roof-gardens, balconies, deep archways, pillared colonnades, spires, battlements, minarets, pinnacles. And when at last the sun rose out of the sea and the great silver-plated dome of the temple flashed back its light, he was almost dazzled. pg.16

In Chapter Three, it is decided that Shasta and Aravis will pretend to be peasant children leading pack horses. In order to do this, they buy ragged clothing for Aravis, and they must cut the horse's tail, which they do with Aravis's scimitar, which is very difficult on the horses. Finally, they decide if they should become separated, they will meet on the far side of the city at a place called the Tombs of the Ancient Kings. With all this decided, they make their way to the gates of Tashbaan.
