I'm a huge fan of the historical neighborhoods OKC has to offer. There's really a great architectural diversity in our city from bungalows, tudors (lots of these north and south of 23rd), all the way to the four square homes in Mesta and elsewhere. Here's an interesting Facebook page about our neighborhoods:

Having said that, my personal favorite is probably Lincoln Terrace because it's HIGHLY underrated and home to some rich history and prestigious homes.

We have many great historical neighborhoods: Heritage Hills, Mesta Park, Lincoln Terrace, Putnam Heights, Gatewood, Las Vegas, Shepherd Historic, Jefferson Park, Paseo, Crestwood, Miller, Cleveland, Denniston Park, etc.
