Question: Are both museums, Chang Lien-Cheng Saxophone Museum and Green Vault, located in the same country?
Sentence (from "Green Vault"): It has some claim to be the oldest museum in the world; it is older than the British Museum, opened in 1759, but the Vatican Museums date their foundation to the public display of the newly excavated "Laocoön group" in 1506.
Relevant evidence: No
