Akal Takht: Located in Amritsar, it is the oldest of the Takhts, and considered supreme among the five. It was set up in 1606 by Guru Hargobind, whose succession as the sixth Guru after the execution of his father, Guru Arjan Dev, is considered a turning point in Sikh history. The Akal Takht, a raised platform that he built in front of the causeway leading to the sanctum sanctorum of the Harmandir Sahib (Golden Temple), symbolised the coming together of the temporal authority and the political sovereignty of the Sikh community (miri) with the spiritual authority (piri). It is seen as the first marker of Sikh nationalism. The Akal Takht is a five-storey building today; the first storey houses the Guru Granth Sahib.
