"V.R. Ramachandra Dikshitar, quoted in Tiru Mayil Kapaleecharam Kumbhabisheka Malar 1982, believed that the great Shiva temple covered the area now occupied by the palace of the Roman Catholic bishop of Madras. This estate, on the south side of San Thome Cathedral, still contains scattered temple ruins and includes a museum. 50 V. Balambal, in Journal of Indian History 1986, Vol. LXIV, Parts 1-3, writes, “According to certain Dutch sources quoted by A. Gelletti, the old town of Mylapore was demolished in 1674 by the order of the King of Golconda and was in ruins. This hypothesis is questioned as some epigraphs 51 specify that the old shore Temple of Kapaleeswara was demolished in the 16th century by the Portuguese and some of the ruins including a broken Vinayaka image are still seen scattered within the demesne of the Mylapore bishop’s palace. It is also said that the remnants of the temple, its pillars, etc., were found immersed in the sea sixty years ago.”"
