The Museum of the History of the Polish Jews in Warsaw, Poland is one of the best museums I’ve ever visited and I’ve visited a lot of museums. It’s a several hours meander through recreated time periods over thousands of years, which immerses you into that period with brilliant veracity. It emphasizes the everyday life at each period, which makes it larger than just a Jewish experience. I recommend a visit to the museum even if you are only interested in the art of exhibits, storytelling, and immersive experiences. — KK

When Spanish conquistadors marched into the island city of Mexico-Tenochtitlan in 1518, they were stunned by what they encountered. The scale, richness, complexity, and advancement of this capital built by the local Aztecs surpassed anything in Spain at the time. I find this 3D virtual reconstructed Portrait of Tenochtitlan on lake Texcoco to reward endless scrutiny. The sliding overlay of modern Mexico City is genius. I am as much stunned by its grandeur as the first invaders. – KK
