A new museum is opening this weekend that could change Oklahoma City forever. The First Americans Museum will welcome the public today. KOCO 5 was live at the museum Friday evening in advance of the grand opening. If you live in the metro, you’ve probably seen the years of construction near I-35 and I-40. The museum represents the more than three dozen tribes in Oklahoma today. Together, they have about 300,000 members. This week, KOCO 5 took Oklahoma City Mayor David Holt for a ride in Sky 5 and flew over the museum."I cannot wait for the people of Oklahoma City to see it — it really will not quite feel the same here in Oklahoma City after this museum is open to the public,” he said. The construction of this building, formerly known as the American Indian Cultural Center and Museum, started in 2006 but came to a sudden stop for years because of low funding after the Legislature refused to allocate more funds. In 2016, the city, state and tribal nations decided to come together to finish the construction of the museum. “It’s awe-inspiring, it’s world-class, you know, it’s Smithsonian-level quality. It’s $175 million dollars and it looks it,” Holt said. This 40-acre museum is now set to share the history of Oklahoma’s 39 tribal nations through cultural diversity and contributions of first Americans. “Nobody has a museum of history and culture of Native Americans that is at this scale,” Holt said. The museum is also special to the mayor in a personal way: He’s a member of the Osage Nation.
