The exhibition concludes at the north side of the first floor gallery. Reliefs of Athenian decrees, impressive portraits, Roman copies of classical masterpieces and depictions of philosophers and historical figures are the exhibits covering the period from the 5th century BC to the 5th century AD. These collections of the Museum include the Sanctuary of Artemis Brauronia, the votives of the Classical and Hellenistic Periods and the votives of the Roman Period.

Numerous statues were placed on the Acropolis, which represented gods, heroes, mythological themes and portraits of famous men. They were often works of well-known sculptors, dedicated by cities, rulers or even citizens. Few have survived and usually in poor condition. Moreover, from the mid-5th century BC stelai were also erected on the Acropolis. These were inscribed with decrees of the Parliament and the Public Assembly of the Athenians. The inscriptions on the stone were the publication of the original records which were written on papyrus or wooden tablets. The decrees are divided into two categories, depending on their content: a) Athenian treaties or alliances with other cities and b) honorary decrees for individuals who had offered services or benefactions to the city.
