The copper-domed building with the terrace gardens surrounding it is the Shrine of the Báb in Haifa, Israel. The neoclassical buildings are the administrative centers of the Bahá'í faith, all in the same area. The fairly simple-looking brick-cornered building with the gardens around it that shows up in quite a few photographs is the Shrine of Bahá'u'lláh near Akka (Akko, Acre), Israel and is the holiest place on Earth to Bahá'ís.
Bahá'u'lláh was banished to Akka by the authorities of the Ottoman Empire in 1868, and passed away there in 1892. During the banishment the local authorities gradually relaxed the restrictions on Him and His family, and He was allowed first to move out of the prison citadel into the city of Akka, and eventually out into the countryside.
The remaining pictures are from various holy places in Akka, mostly places where Bahá'u'lláh and His family stayed during their exile or simple tourist pictures from Haifa.
