It dominates in Syntagma Square. It was built as the Palace of Othonas, the first king of Greece. Its construction lasted from 1836 until 1842. The second king, Georgios the 1st also stayed in this Palace. During his reign, two massive fires destroyed the building in such extent that it was inappropriate for royal use. The government of 1924 was the one that decided the Greek Parliament should be housed there. The reconstruction works were finished in 1934 and its interior was designed by the architect A. Kriezi. The Parliament houses national treasures such as the first Constitution of Greece and many valuable paintings. It is also worth to visit its great library.
