Colonial churches
No British governmental centre could be complete without a church, and in 1927 work began on the Church of the Redemption, east of Parliament House. Designed by Russell's successor, Henry Medd, the robust structure owes more than a passing nod to Lutyens with its high curved vaults, and subtle yet dominant domed tower - it appealed so much to the then-viceroy, Lord Irwin, that it became known as "Viceroy's Church". The exterior is plain and boldly linear, while within, high rounded arches and shafts of strong light streaming through crescent windows impart an overwhelming sense of space. A company of angels looks down from the curved roof above the altar.

Birla Mandir

Quwwat Ul Islam Mosque
The contruction of the mosque was begun in 1193 AD by Qutb-Ud-Din Aibak of the Mamluk(or the slave) dynasty and completed in 1197 AD. A massive stone screen of lofty five arches was put up in front of its prayer hall, which imparted an Islamic character to the building. The screen is beautifully carved with borders of inscriptions and geometrical and arabesque designs. Subsequently, the mosque was enlarged by two later rulers, Shansuddin Iltutmish (1211 - 1236 AD) and Alauddin Khalji (1296 - 1316 AD). The screens of these two sultans are carved with purely islamic motifs abounding in geometric patterns. This mosque is also known as the Quwwat Ul Islam (Might of Islam), as this is the earliest mosque in the country that has survived the blow of time. It consists of a rectangular courtyard, 43.2 sq metres by 32.9 sq metres, enclosed by cloisters which were erected by Qutb-Ud-Din Aibak, with carved columns and other architectural members of twenty similar Hindu and Jain temples.

Iron Pillar
The seven-metre-high pillar stands in the courtyard of the Quwwat-ul-Islam mosque and has been there since long before the mosque's construction. This temple displays a number of relics that has enabled historians to determine its origin. For instance, an inscription in sanskrit of six lines clearly indicates that it was initially erected outside a Vishnu temple, possibly in Bihar and was raised in memory of the Gupta King Chandragupta Vikramaditya, who ruled from 375 to 413. It is supposedly built in the same era. There's even a hole on the top where there might have been a sculpture of Garuda, Vishnu's celestial vehicle. The inscription does not tell us that how it was made. The quality of the iron used for constructing the pillar is exceptionally pure and has not rusted even partially after 2000 years. It is said that if you can encircle the pillar with your hands whilst standing with your back towards it, your wish will be fulfilled. But the pillar can't be encircled any longer, since the ASI has protected it with a railing.
