Is there a reward or virtue for visiting Mount Uhud or the Archers, or for intentionally going to the Mosque of Hamza ibn Abd al-Muttalib to pray therein?

The permissible places to visit in Medina are: The Prophet's Mosque, the tomb of the Prophet (peace be upon him), the tombs of his two companions, Al-Baqi' cemetery, Quba Mosque, and the cemetery of the martyrs of Uhud. Anything other than these is not permissible to visit. Hamza Mosque, which is near the tombs of the martyrs of Uhud, is not permissible to visit for prayer therein. However, there is no harm in visiting Jabal al-Rumah (Mount of Archers) for observation.
