The main permanent exhibition at the Literature Museum Sándor Petőfi is devoted to the life and work of the museum patron, Sándor Petőfi, one of the most important and outstanding Hungarian poets. The exhibition presents the writer's short but turbulent life through the prism of his works. Regularly organized temporary exhibitions are devoted to other important Hungarian authors and literary trends.
The museum's collection includes numerous unique exhibits documenting the history of Hungarian literature. These include manuscripts and first editions of the most important Hungarian works, among others manuscript of the poem "On the banks of the Danube" by József Attila or "National Song" by Petőfi, one of the most patriotic Hungarian poems.
The museum is based in a classical style palace built by György Károlyi in the 1830s. In one of the museum's small rooms there is the "Ady's Altar", a sculpture by Miklós Melocco dedicated to the poet Endre Ady.
