According to an early Sikh tradition the foundation stone of the Harimandir now called the Golden temple was laid by Guru Arjan Dcv himself. This version is carried by the all written Sikh sources up to the late nineteenth century. The generally recorded account is that Guru Arjan Dev laid the foundation of Harimandir on 1st Magh Samvat 1645/AD. 1588. However, a later but now commonly accepted Sikh tradition is that the foundation of the temple was laid at the request of Guru Arjan Dev by a Muslim Pir Mian Mir of Lahore in Samvat 1645 BK. 

Hope this helps:)
