to show respect for Mother Earth. The CMHR website had two webcams available for the public to watch the construction as it progressed. For the construction of the Hall of Hope, full of illuminated alabaster ramps, more than 3.500m² and 15.000 tiles of alabaster were used, making it the biggest project ever done with alabaster. On 3 July 2010, Elizabeth II, Queen of Canada, unveiled the building's cornerstone. The stone bears the Queen's royal cypher and has embedded in it a piece of stone from the ruins of St. Mary's Priory, at Runnymede, England, where it is believed the Magna Carta was approved in 1215 by King John. Exhibition and facilities On the fifth floor is the Carte International Reference Centre, the CMHR library "devoted to collecting and providing access to resources that support human rights learning and research." Exhibit design The CMHR worked with exhibit designer Ralph Appelbaum Associates (RAA) from New York to develop the inaugural exhibits of the museum. RAA indicated that the galleries throughout the CMHR would deal with various themes including the Canadian human rights journey, Indigenous concepts of human rights, the Holocaust, and current human rights issues. The CMHR's team of researchers worked with RAA to develop the inaugural exhibits. In January 2009, lawyer Yude Henteleff was appointed to chair the museum's content advisory committee, made up of human rights experts and leaders from across Canada. The committee was a key part of the museum's first large-scale public engagement exercise. Through a cross-country tour from May 2009 to February 2010 called "Help Write the Story of the Canadian Museum for Human Rights", CMHR researchers visited 19 cities and talked to thousands of people about their human rights experiences and what they wanted to see in the museum. This consultation process was led by Lord Cultural Resources, based in Toronto. On 5 March 2013, a story produced by CBC TV (Manitoba) mentioned a document, "Gallery Profiles" (dated 12 September 2012), that confirmed some of the CMHR's proposed contents. The museum's largest gallery is dedicated to Canadian content, while a thematic approach is taken throughout all of its galleries. Galleries The museum has had 10 core galleries since the time of its opening in September 2014: What are human rights? Indigenous perspectives. This includes a "circular movie about First Nations concepts of rights and responsibilities to each other and the land." Curator Lee-Ann Martin described contemporary
