Gurudwara Bangla Sahib; (Punjabi: ਗੁਰਦੁਆਰਾ ਬੰਗਲਾ ਸਾਹਿਬ) is one of the most prominent Sikh gurdwara, or Sikh house of worship, in Delhi, India and known for its association with the eighth Sikh Guru, Guru Har Krishan, as well as the pool inside its complex, known as the "Sarovar." It was first built as a small shrine by Sikh General Sardar Bhagel Singh in 1783, who supervised the construction of nine Sikh shrines in Delhi in the same year, during the reign of Mughal Emperor, Shah Alam II. It is situated near Connaught Place, New Delhi on Baba Kharak Singh Marg and it is instantly recognisable by its golden dome and tall flagpole, Nishan Sahib. Located next to it is the Sacred Heart Cathedral.
Humayun's tomb (Persian: آرامگاه همایون Maqbara e Humayun Turkish: Hümayun Kabri) is the tomb of the Mughal Emperor Humayun in Delhi, India. The tomb was commissioned by Humayun's son Akbar in 1569-70, and designed by Mirak Mirza Ghiyas, a Persian architect chosen by Bega Begum.It was the first garden-tomb on the Indian subcontinent, and is located in Nizamuddin East, Delhi, India, close to the Dina-panah citadel also known as Purana Qila (Old Fort)that Humayun founded in 1533. It was also the first structure to use red sandstone at such a scale. The tomb was declared a UNESCO World Heritage Site in 1993, and since then has undergone extensive restoration work, which is complete. Besides the main tomb enclosure of Humayun, several smaller monuments dot the pathway leading up to it, from the main entrance in the West, including one that even pre-dates the main tomb itself, by twenty years; it is the tomb complex of Isa Khan Niyazi, an Afghan noble in Sher Shah Suri's court of the Suri dynasty, who fought against the Mughals, constructed in 1547 CE. The complex encompasses the main tomb of the Emperor Humayun, which houses the graves of Bega Begum herself, Hamida Begum, and also Dara Shikoh, great-great-grandson of Humayun and son of the later Emperor Shah Jahan, as well as numerous other subsequent Mughals, including Emperor Jahandar Shah, Farrukhsiyar, Rafi Ul-Darjat, Rafi Ud-Daulat, Muhammad Kam Bakhsh and Alamgir II. It represented a leap in Mughal architecture, and together with its accomplished Charbagh garden, typical of Persian gardens, but never seen before in India, it set a precedent for subsequent Mughal architecture. It is seen as a clear departure from the fairly modest mausoleum of his father, the first Mughal Emperor, Babur, called Bagh-e Babur (Gardens of Babur) in Kabul (Afghanistan). Though the latter was the first Emperor to start the tradition of being buried in a paradise garden. Modelled on Gur-e Amir, the tomb of his ancest
