This archaeological museum is housed in the enchanting 12th-century Igreja de São João de Alporão. Among the stone carvings, azulejos and rotating exhibits is the elaborate tomb of Dom Duarte de Menezes, who died in 1464 in a battle against the Moors in North Africa. It’s quite grand – especially considering that once the Moors had finished with him, all that was left for burial was a tooth!
