The Kharakhorum Museum is a modern building that does a good job of giving substance to what is otherwise an invisible city. Karakorum's ruins lie mostly underground, and without the museum's artefacts and interpretive displays it can be hard to grasp the scale and sophistication of the 13th-century capital. Exhibits include pottery, coins, trade goods, tools, and fragments of architectural decoration recovered from ongoing excavations — evidence of a cosmopolitan city that once hosted traders, diplomats, and craftsmen from across Eurasia.
The star exhibit is a large granite turtle sculpture — one of four that originally marked the boundaries of ancient Karakorum, each sitting at a cardinal point of the city. The turtles were believed to protect the city from floods; one still stands in the open just outside the monastery wall. Seeing the museum's copy alongside the original puts the lost city in useful perspective. The building itself is well laid out and the English signage is reasonable by Mongolian provincial standards.
