They are a tribal society. What matters is loyalty to the ruling family leaders to whom they pledge absolute oath of loyalty, constantly offering extravagant praises. So, they preserve Saud heritage, old villages, houses and palaces. They don't care about Arab, Muslim, or the Prophet's heritage, they have destroyed the early heritage sites of Arab Muslims. Other than Maqam Ibrahim which goes back to the founding of Kaaba, I don't think there is a monument or building preserved in Makkah from the time of the Prophet and his companions. Maybe one or two, would like to know.
