Senuseret I (Part III) and Karnak Temple.
The building projects of Senuseret I were the most widespread and splendid of any ruler since the Old Kingdom. Buildings up and down the Nile valley were begun under his rule, including monuments at Karnak, Heliopolis and Elephantine.
The king's pyramid at al-Lisht attempted an innovative building method, with mixed success.
