During the aftermath of the 1755 Lisbon earthquake, it was determined that there was superficial damage and no fear of collapse, but a number of repairs were completed between 1755 and 1756. Under supervision of the architect João Pedro Ludovice, the "Casa Real de Campo de Belém" (Belém Royal Country House) or "Palácio das Leoneiras" also received attention. Work included replacing tile and repairs to the greenhouses and stables. Similarly, around 1770, architect Mateus Vicente de Oliveira undertook reconstruction of the total estate. This was the beginning of several small projects within the residence that included the painting of the "Sala das Bicas", the replacement of azulejo tiles along the southern veranda (1778), and construction of the birdhouses (1780). Initial construction of the Neoclassical horse training arena designed by the Italian Giacomo Azzolini began in 1828. The space is now occupied by the National Coach Museum
