Art museums have extremely finicky hours, always closed on the one day you are visiting a city far away. Starting today and running until April 26th the Newark Museum will give you no excuse as to why you can't visit: they are open 100 hours straight in honor of their 100th birthday. Admission to this great museum is free and activities are a plenty. There is a midnight flashlight tour of the Ballantine House, laser light shows and overnight films, dinosaur day, live music, early morning yoga and morning prayers at the Tibetan altar.
The Newark Museum is a gem that sometimes gets lost in the shadow of New York's mega museums. They have one of the largest collections of Tibetan art outside of Tibet, and since the 1930's have had a gorgeous consecrated Tibetan Buddhist altar, most recently renovated in the 1990's by a monk who worked on it for months, offering visitors the chance to observe his daily progress. The museum began in 1909 with an assortment of Japanese artworks, and later grew to included the Ballantine House, former home of a Ballantine Brewery heir. Like many small museums they have a collection of individual interests determined by idiosyncratic curators and local donors. For me, that is what makes a visit here so special.
