Imamzadeh Yahya – Semnan

Fronted with splendid blue tiling and filled with dazzling mirror-mosaics, this mostly contemporary imamzadeh just off the bazaar entombs Yahya bin Musa Kazim, one of the brothers of the eighth imam. The men's side prayer hall is floored in jade-green soapstone and the graves of martyrs from the Iran-Iraq war. The tomb itself is showered with banknotes. The mausoleum clock chimes like an electronic Big Ben.
