There is a ruin in the locality behind the Janamasthan of Jagat Guru at Nankana. This ruin is known as Dhaular Thia. On it is the grave of the person who was the first to recognize Sat Gur Nanak Dev Ji as the one chosen by God. He had bestowed half of his estate to Gurdwara which is still in the name of Gurdwara Sahib. This mud grave is a great milestone of history. Many descendants of Rai Bular have been notable politicians. Rai Mansab Ali had been a minister. Similarly Rai Mohammad Bashir Bhatti has been a member of Pakistan National Assembly.
