Originally known as Akal Bunga, the building directly opposite to the Harmandir Sahib was founded by sixth Sikh Guru, Guru Hargobind, as a symbol of political sovereignty and where spiritual and temporal concerns of the Sikh people could be addressed. Along with Baba Buddha and Bhai Gurdas, the sixth Sikh Guru built a 9-foot-high concrete slab. When Guru Hargobind revealed the platform on 15 June 1606, he put on two swords: one indicated his spiritual authority ("piri") and the other, his temporal authority ("miri").
