Memorial JK, Museum and presidential memorial in Monumental Axis, Brazil

Memorial JK is a museum, mausoleum and cultural centre on the Monumental Axis in Brasília, designed by Oscar Niemeyer. Its exterior is a block of white marble with few openings. Outside, a 4.5-metre statue of Juscelino Kubitschek by Honório Peçanha, shown waving, stands on a 28-metre reinforced-concrete pillar beneath a curved shell.

Sarah Kubitschek commissioned Oscar Niemeyer to design the memorial in 1976, after her husband's death that August. President Ernesto Geisel blocked construction until João Figueiredo took office in 1979. A public fundraising campaign, "Você constrói o Memorial JK", financed the work, which took 17 months and was inaugurated on 12 September 1981, Juscelino's 79th birthday.

The memorial's name honours Juscelino Kubitschek, known as JK, and the site is run by the civil society his granddaughter Anna Christina Kubitschek Barbará Pereira directs. Inside, the Márcia Kubistchek Auditorium, named for his daughter, holds 310 seats arranged to form the letter K, and hosts music, theatre and choir performances. The hall carpet was woven by artisans from Diamantina, and the flags of Brazil, the Federal District and Minas Gerais stand in front of the building.

The building opens Tuesday to Sunday in the morning and closes in the early evening, with Monday closed. The entrance is right next to the parking area, and the rooms are on ground level or accessible via ramps.

The curved shell above the statue was originally designed as two shells, one rising from below and one in the executed position. Niemeyer removed one after the military saw a hammer and sickle in the shape; he denied the reference for the rest of his life. The concrete pedestal is 28 metres high and the statue by Honório Peçanha measures 4.5 metres.
