There is a historic district known as Longfellow Avenue that has a series of old brownstone homes. Many were neglected and in disrepair but the city has renovated these homes with private and public funding.
There are other historic districts in the Bronx there is the Clay Avenue historic district with there beautiful brownstone.
The city has restored a lot of the vacant abandoned burn down lots of the 1970's and have restored neighborhoods.
