Space and time
You can loose hours in the Metropolitan Museum of Art. The collections are amazing and incredibly diverse. The Temple of Dendur exhibit is one of our favorites. A 15 B.C. Nubian temple given to the museum by Egypt, and installed in a beautifully designed modern space with a massive reflecting pool and sloping wall behind it that represents its original location. It's great place to take a little break when you visit the museum and ponder space and time...
