European sailors , for whom the temple was an importa nt landmark , enabling them to keep out of the dangerous shallows of the Orissa coast ( they nearly had it turned into a lighthouse ) , called it the Black Pagoda in order to be able to distinguish it from the White Pagoda of Puri 's whitewashed Jaggannath Temple further down the coast .
The temple was called the Diamond Pagoda since it was diamond shaped .
