This museum in Warsaw, Poland, by Finnish studio Lahdelma & Mahlamäki Architects has a deep, cavernous entrance hall that cuts right through the building (+ slideshow).

Helsinki-based Lahdelma & Mahlamäki Architects collaborated with Polish firm Kuryłowicz & Associates to build The Museum of the History of Polish Jews.

Located on the former site of the Second World War Warsaw Ghetto, the museum is used for a combination of research, education, exhibitions and culture relating to the Jewish heritage.

The museum is also adjacent to the memorial commemorating the Warsaw Ghetto Uprising of 1943, separated by a large paved square.

A cavernous entrance hall is the central feature of the building, with its smooth sprayed-walls curving in bulbous shapes from the travertine floor to the ceiling.

"To the best of our knowledge it is the biggest uniform, geometrically double-curving surface that has ever been realised," said architect Rainer Mahlamäki.

"The design of the curved walls, which are bearing structures, was particularly challenging," he added.

The green-tinged glass facade reflects patterns of light throughout the main entrance and ground-floor information centre.

An exhibition space takes up an entire floor of the three-storey building, plus there's a library, restaurant, cafeteria, shop, large auditorium, office spaces and classrooms.

Perforated copper and silkscreen-printed glass panels printed with Latin and Hebrew text clad the exterior. Designed by Israeli artist Klementyna Jankiewicz, the text says "polin", which means "rest here" in Hebrew.

On the ground-floor facade, a triangular shape cut from the glass panels forms a corner window.

The museum opened in April this year and featured its first exhibition last month.

Other stories about museums we've recently featured include one with walls of dark concrete referencing the colours of volcanic rock and lava, a maritime museum with a zig-zagging roof and wooden cladding and a design for the new Marrakech Museum for Photography and Visual Arts.

The Museum of the History of Polish Jews

The origins of the Museum of the History of the Polish Jews go back to the mid- 1990s, when the founding director of Tel Aviv’s Diaspora Museum and the Holocaust Museum in Washington DC, Yeshayahu Weinberg, convened an in- ternational working group to plan a new museum dedicated to the history of the Polish Jews. Some 150 researchers from different countries in Europe, Israel and North America participated in gathering the material on the history and lives of the Jewish people.

By the year 2003, the fundamental idea and preliminary exhibition plan for the museum had been completed. In spring 2005 an international architectural competition was held for the design of the building to house the museum.

The selection of the participants of the architectural competition was based on expressions of interest. Among the architects invited to join the second stage of the competition were Studio Daniel Libe- skind, Kengo Kuma & Associates, Zvi Hecker Architects, Peter Eisenman, David Chipperfield and six other groups, including Lahdelma & Mahlamäki Architects.

The international members of the jury included among others, Professor Kenneth Frampton. The proposal “Yum Suf”, “Sea of Reeds”, by Lahdelma & Mahlamäki Architects was declared winner in summer 2005.

Warsaw has been one of the most important cities for Jews; before the Second World War there were half a million Jewish inhabitants in the city. The museum’s plot is about a kilometre away from the old centre of Warsaw. The site is a park surrounded by residential buildings. The park located there today, named after the former Chancellor of the Federal Republic of Germany, Willy Brandt, formed the core of the Warsaw ghetto.

The Memorial to the Warsaw Ghetto Uprising is erected in the park. The Memorial to the Warsaw Ghetto Uprising located next to the museum is one of the key points of departure for the design. The square in front of the memorial and the museum are sufficiently close together and their dimensions are mutually compatible: the square and the museum building will form a new urban space.

The main entrance is placed on the memorial side of the building, from where a series of spaces continues via a bridge towards the landscape. The basic form of the building is compact and simple, reducing its footprint in the surrounding park.

The competition jury stated in its evaluation, that the concept had been realised “without unnecessary rhetoric, with simplicity and elegance”. The name of the competition proposal, “Yum Suf”, symbolically refers to the architecture of the main hall. The inspiration for the space has been the legends of the Old Testament, although at the same time forms of the hall refer to the universal and abstract phenomena of nature.

The main hall is the most important element in the architecture of the building; a pure and silent space introducing the museum to the visitors. The museum building is a multifunctional centre for research, exhibition, education and culture relating to the Jewish heritage.

The core exhibition area comprises a hall that resembles an only half-finished space, almost five thousand square metres in area, beneath the main lobby. The exhibition will present the different forms and periods of Jewish culture from the Middle Ages on until today– the holocaust is only one of the themes of the exhibition.

The message will be conveyed in the form of a narrative exhibition, making use of reconstruction, moving pictures, and various constructed milieus and to minor extent also historical objects. The plan for the core exhibition was part of the competition source material, and the functional requirements and gallery division for the exhibition were to be considered in designing the building. There is to be a special focus on young people. The museum expects half a million visitors annually.

The frame of the building is cast-in-situ concrete. The free-form walls and the curving shapes of the roof connecting to them form part of the frame system. The total thickness of the steel structured and sprayed concreted wall is about 60 cm. The design of the curved walls, which are bearing structures, was particularly challenging.

To the best of our knowledge it is the biggest uniform, geometrically double curving surface that has ever been realised. The design was partly implemented with assistance of software developed by the designer specifically for this project by Markus Wikar / Architects Lahdelma & Mahlamäki.

The outer layer of the double facade is to be clad with laminated glass panels and pre-treated, perforated copper panels. The building permission drawings were handed over to the City of Warsaw in the spring 2008.

The foundation stone was laid in June of 2009. The museum launched its activities the 19th of April 2013. The Core Exhibition will open to the public in September 2014.
