On the east side of the Thaj Mahal stands the 
        twin of the Mosque, a parallel structure also made of red sandstone, referred 
        to as the jawab, or "
answer". Because it faced away from the 
        Mecca, it was never used for prayer. Its presence there has always been something 
        of an enigma. Was it a caravanserai for pilgrims, or a meeting hall before the 
        faithful gathered before prayer? More p lausible is the theory that its purpose 
        was purely architectural, to counterbalance the Mosque and preserve the symmetry 
        of the entire design on the platform. 
    
        The jawab is similar to the Mosque. However, it does not contain the accessories which go with a mosque, and, instead of Koranic inscriptions, there are beautiful flower designs and other decoration effectively done in white marble on the red sandstone background. On the floor between the building and the mausoleum there is a full size reproduction of the pinnacle adorning the Tadj Mahal. This gives some idea of the true proportions (31 ft.) of what from below appears to be a tiny thing.
