The Tree Museum is not a building. It is a narrated walk of 100 trees of 24 species along the Grand Concourse between 138th Street and the Moshulu Parkway in the Bronx. The public art project was designed by visual artist Katie Holten in 2009. The audio guide has been discontinued but you can still walk the project and gaze at the trees. Download the map.
There are "more than 60 species of trees currently growing along the Grand Concourse. This is more than 70 percent of the species we plant citywide, making the Concourse not only grand, but also diverse," said Jonathan Pywell, Bronx Senor Forester, NYC Dept. of Parks & Recreation to Katie Holten. The 24 species featured in the Tree Museum are:
Prunus serrulata 'Kwanzan'
Platanus x acerifola
Northern red oak
Sophora japonica [now Styphnolobium japonicum]
