The Rietveld Schröder House was built in 1924 by Dutch architect Gerrit Rietveld for Mrs. Truus Schröder-Schräder and her three children. It constitutes both inside and outside a radical break with all architecture before it. The house is one of the best known examples of De Stijl-architecture and arguably the only true De Stijl building. Mrs. Schröder lived in the house until her death in 1985. The house was restored by Bertus Mulder and now is a museum open for visits. It is a listed monument since 1976 and UNESCO World Heritage Site since 2000.
Inside there is no static accumulation of rooms, but a dynamic, changeable open zone. The ground floor can still be termed traditional; ranged around a central staircase are kitchen and three sit/bedrooms. The living area upstairs, stated as being an attic to satisfy the fire regulations of the planning authorities, in fact forms a large open zone except for a separate toilet and a bathroom. Rietveld wanted to leave the upper level as it was. Mrs Schröder, however, felt that as living space it should be usable in either form, open or subdivided. This was achieved with a system of sliding and revolving panels. Mrs Schröder used these panels to open up the space of the second floor to allow more of an open area for her and her 3 children, leaving the option still of closing or separating the rooms when desired. When entirely partitioned in, the living level comprises three bedrooms, bathroom and living room. In-between this and the open state is a wide variety of possible permutations, each providing its own spatial experience.
The facades are a collage of planes and lines whose components are purposely detached from, and seem to glide past, one another. This enabled the provision of several balconies. Like Rietveld's Red and Blue Chair, each component has its own form, position and colour. Colours were chosen as to strengthen the plasticity of the facades; surfaces in white and shades of grey, black window and doorframes, and a number of linear elements in primary colours.
There is little distinction between interior and exterior space. The rectilinear lines and planes flow from outside to inside, with the same colour palette and surfaces. Even the windows are hinged so that they can only open 90 degrees to the wall, preserving strict design standards about intersecting planes, and further blurring the delineation of inside and out.References:
Roman Walls of Lugo are an exceptional architectural, archaeological and constructive legacy of Roman engineering, dating from the 3rd and 4th centuries AD. The Walls are built of internal and external stone facings of slate with some granite, with a core filling of a conglomerate of slate slabs and worked stone pieces from Roman buildings, interlocked with lime mortar.
Their total length of 2117 m in the shape of an oblong rectangle occupies an area of 1.68 ha. Their height varies between 8 and 10 m, with a width of 4.2 m, reaching 7 m in some specific points. The walls still contain 85 external towers, 10 gates (five of which are original and five that were opened in modern times), four staircases and two ramps providing access to the walkway along the top of the walls, one of which is internal and the other external. Each tower contained access stairs leading from the intervallum to the wall walk of town wall, of which a total of 21 have been discovered to date.
The defences of Lugo are the most complete and best preserved example of Roman military architecture in the Western Roman Empire.
Despite the renovation work carried out, the walls conserve their original layout and the construction features associated with their defensive purpose, with walls, battlements, towers, fortifications, both modern and original gates and stairways, and a moat.
Since they were built, the walls have defined the layout and growth of the city, which was declared a Historical-Artistic Ensemble in 1973, forming a part of it and becoming an emblematic structure that can be freely accessed to walk along. The local inhabitants and visitors alike have used them as an area for enjoyment and as a part of urban life for centuries.
The fortifications were added to UNESCO"s World Heritage List in late 2000 and are a popular tourist attraction.
