In 1833 Athens becomes the capital of the new Greek state. The Revolution of 1821 has left almost inhabitable and half destroyed. In the following year, after an edict by king Otto, started the city-planning proposal and the erection of public buildings with the explicit order to protect the archaeological sites. For the next 30 years Athens experiences a building frenzy and until 1896, the year of the first modern Olympic Games, its aspect has changed radically, with the addition of impressive, beautiful buildings and infrastructure works.
