The „Portmoneum“ is named after its owner Josef Portman, a Czech collector, printer and philanthropist. In the 20´s, the house was decorated with „devilish“ wall paintings and carved furniture by Josef Váchal. After the Velvet revolution, the site was bought by the publisher Ladislav Horáček. A challenging restauration followed and the private Josef Váchal Museum was established. Its phenomenon shaped the cultural identity of Litomyšl, sparked the collaboration with renowned architects and inspired the founding of The School of Restauration.
After the death of Ladislav Horáček, the Pardubice region bought the monument for the Regional Museum in Litomyšl. Approaching the original architect, they finished the renovation which had been left partially incomplete in the 90‘s. They strengthened the foundations, reinstalled the slate roof and refurbished the facilities. The attic was converted into a creative workshop and a screening space for a unique videomapping about Josef Váchal.

The most valuable parts of the house are two rooms with Váchal´s wall paintings. These were firstly rehabilitated in the 90‘s and newly restored and conserved in 2020 by Jiří Látal.
The chosen materials correspond with the historical value of the building: slate, brick paving, oak wood, secondary components from demolitions. The roof is insulated with wood fibre, the gables with calcium silicate boards.
The building stability was ensured by deepening the foundations in the southern half of the house and by helical reinforcement of perimeter walls. The ceilings were strengthened with new beams, the damaged or temporary aesthetically unfit elements of the roof frame replaced.
The damp walls in the nothern part were injected; the cellar walls tanked from the interior. The capillary active render reassures a faster drying of walls. The surfaces are covered with lime plaster and painting.
