Khirkee Masjid, Delhi

The Khirkee mosque was built by Khan-i-jahan Junan Shah the prime minister of Feroze Shah Tughlaq.

Gordon Risley Hearn in his The Seven Cities of Delhi (1906) after describing the mosque as 'a very fine one' says:
In plan it is square and within the encircling wall there is a colonnade; but the interior, instead ofbeing left open, as other mosques of the time were, has arcades in the shape of a cross; fourcourts are thus left open… the windows in the outer walls are closed by heavy sand stonegrilles… (the) mosque is well worthy of inspection…

Do you know why it got such a name?

The Masjid has an entrance on all three sides, except on the western side. It has a pillared courtyard, which is divided in to 25 neatly designed squares which can accommodate nine squares within them. The four squares on the diagonals are left open to let in the much needed air and light. Glancing from the out side, the Masjid gives an impression of a moat or a fort with a moat located in its inside.

It has got its name because of the numerous windows.
Can anyone give the info of how to reach there?
