How does Gulliver describe the country where the giants live?

Gulliver describes the country as being a peninsula with a large mountain at the end touching land. The people fish mostly in the rivers, because the sea only has normal size fish, but occasionally, a whale is caught from there. The main city is 54 miles long and holds 600,000 people. Gulliver also describes the beautiful temple, which would be much smaller than a European temple, if it were of the same proportions.
