at, in

To determine which words to use in the sentence, consider the following grammar rules:

1. Use "in" to indicate a larger area or country.
2. Use "at" to indicate a specific point or location within that area.

In the given sentence, "Kilwa" refers to a specific location. Therefore, you should use the word "in" before "Kilwa" to indicate the larger area.

The correct sentence would be: The Husuni Kubwa was built in Kilwa in 1300.
