in addition to various ancient greco-roman works of art and literature depicting the queen, cleopatra's legacy has partially survived in some of her ambitious building programs in egypt utilizing greek, roman, and egyptian styles of architecture. she established a caesareum temple dedicated to the worship of her partner julius caesar near the palatial seafront of alexandria. its entrance was flanked by 200-ton rose granite obelisks, monuments placed there by augustus in 13/12 bc. these were later known as cleopatra's needles and were relocated to new york and london in the 19th century. in conjunction with renewing a grant of asylum to jews in egypt and the pro-jewish policies of julius caesar, cleopatra also erected a synagogue in alexandria. the city required extensive rebuilding following the civil war with her brother ptolemy xiii, including necessary repairs to the gymnasium and the lighthouse of alexandria on the island of pharos. it is not known if cleopatra made significant repairs or alterations to the library of alexandria or the royal palace, although lucan hints at the latter. cleopatra also began construction of her tomb (finished by augustus) in the same palace precinct as the tomb of alexander the great. although the exact location of both of these is still unknown, cleopatra's tomb may have served as the model for the mausoleum of augustus and that of later roman emperors.
