Premise: The fort, which was taken by Lord Cornwallis and Colonel Arthur Wellesley (the Iron Duke with the rubber boots), no longer stands today, but the sultan's summer palace, Darya Daulat Bagh, has been preserved and made into a museum honoring the brave resistance of Tipu and his father, Haidar Ali.

Hypothesis: The sultan's summer palace still exists, but the fort is gone.
