New Jersey is a busy state, and many of its most charming small towns have since been transformed into bustling modern metropolises. That can mean great things for the town - but sometimes you want to step back in time to a simpler time and place. Fortunately, there's one town in New Jersey where some things never change. Allentown, a town of just over 1,700 located not far from Trenton in western New Jersey, might just be the most historic small town in New Jersey.

Not only is there a huge historic district with beautifully preserved buildings - some dating back to the 1800s - but the whole town has a retro feel that makes for the perfect day trip. You'll encounter stunning architecture, beautiful main streets, and businesses that you didn't know were still operating. Read on as we'll tell you how it all comes together in downtown Allentown, NJ, one of the most memorable day trips you can take!

Allentown is one of the most beautiful towns in New Jersey, and it's also one of the most historic.

The Historic District in downtown Allentown, NJ is spread over 17 acres, and features 219 buildings dating back to the 1800s.

The most famous building in Allentown is definitely the Allentown Mill, which was a functioning grain mill back in 1855.

Today, the structure has been preserved - and it's home to The Moth Coffeehouse, one of the most unique places to get a cup of joe around.

Fresh-baked pastries are available as well, and you'll definitely want to start your Allentown day here.

Many of the businesses around town are truly unique, like Bloomers 'n Things - an old-school florist and pottery shop.

The most beautiful spot in town might be the Ashford Estate, a stately mansion now serving as a wedding venue.

The best place to eat in town is La Piazza, an old-school Italian joint that oozes tradition.

The old-school atmosphere here makes you feel like you're eating in Little Italy in decades past.

The pizza, pasta, and other Italian specialties are worth the trip to Allentown on their own - but there is so much more to see and do here that you'll want to take the full day.
