Tourism in Andhra Pradesh mainly centres round Hyderabad and Tirupati. It is worth mentionable that the monuments of Hyderabad have great influence of Islamic architecture while the influence of Hindu mythology could be distinctly seen in the myriad of Tirupati temples. The state also has many monuments built by medieval rulers like Kakatiyas of the 13th century and Qutub Shahi kings of 16th and 17th century. The best example is available in the form of Golconda Fort.
