Originally owned by the wealthy merchant Georgi Mavridi, this house is an example of Plovdiv Symmetrical Revival Period architecture. Due to the steep terrain upon which it was built, the house has three floors on the front side, and only two in the back. The ground floor has an irregular shape, which is remedied on the second and third floors, each extended over the lower one like a balcony. In 1833, notable French writer, poet and politician Alphonse de Lamartine stayed at this house for 3 days on his way back from a trip to the Orient. The house was since named after him, and one of its rooms houses a permanent exhibition dedicated to the poet. The house is also the creative headquarters of the Bulgarian Writers’ Union.
