Where are we going today?

Do you love history?  Do you love wandering around pieces of history, imagining who used to live and work in those places?  Even kids just like you?

Fort Knox is one of New England's better preserved fortifications.  History is just oozing from every brick and cannon battery (yes - they had cannons!).

You can learn all about all the invasions, wars, revolutions and the War of 1812.  You will read all about the engineers who designed the incredible fort, and the generals who fought to protect it.

Did you know it costs nearly $1 million to build it!?  AND it took nearly 25 years to build! (Here's a fun fact - when they stopped building it in 1869, it STILL wasn't finished!)

A very fun and fast elevator ride away from the fort is the Penobscot Narrows Observatory where you can enjoy pretty spectacular views from the top!  You will be 420 feet up, and then you take your time going up the last two floors so you can try and spot all the famous landmarks - which ones do you recognize? 

Keep an eye out for the information panels as you walk around the fort - they will tell you all the cool facts and stories about what happened where you are standing.  Then you can use your imagination and picture it happening all around you!

We love history because we can feel it come to life as we experience it.  Can you?

Any Top Tips?

The fort occasionally hold Civil War reenactments. Keep and eye out for these listed if you want to experience it. (you can also participate!) .

Need a little extra help?

The gift shop, visitor's center, picnic areas and restroom are handicap accessible. If you do use a wheelchair you can access the inner fort, you will find the original granite steps and stairways in other parts of the fort will limit your access. .

    Fort Knox is one of the best civilwar forts in Maine!. I was there yesterday and took may pictures and got lost a couple of times. Ended up at a dead end. I could see other people walking up in but they couldn't see me. I could have scared the crap out of them.lol. I've heard it to be haunted too so I asked the spirits to give me a sign over&over without any luck. But until I got to an area near the ditch area where the hallways turn to gravel floors I could hear boot steps which at first I thought were my own. But when I stopped they would continue...Read More

    I was there yesterday and it was a great day!. Very beautiful day and I can't believe the great stone and brick work they did for each port and window for cannon fire how to port out the smoke with all the chimneys. All the different hallways and one deadened. I thoutht it was kinda strange. I could see other people walking up to the fort. I could have scared the crap out of them.lol. but it's a great place to visit!.. so much history there and I wish I had more time there. I was by myself like usual but had a good time still. I heard it's haunted...Read More

    Beautiful bridge. Access via the adjacent fort (which is rather interesting too). Probably not good for those afraid of heights.

But until I got to an area near the ditch area where the hallways turn to gravel floors I could hear boot steps which at first I thought were my own. But when I stopped they would continue for 3-4 steps. So I first thought that someone was walking up behind me. But noone was there!.?. Only 5 cars there yesterday when I was there. So not many people there. I was alone in the dark. I just sat there for a few minutes. I give ghost hunters credit for walking around in the dark in that place. It's hard to walk around in the daylight let alone the pitch dark. What a great place!. Everyone needs to visit it.

I heard it's haunted and called out for anyone to give me a sign. But time after time nothing. Until I got to the area of the ditches area. Where the long dark hallway with gravel covers the ground I heard boot steps behind me kinda echoing but sounded like my footsteps!. I thought it was someone behind me coming up but I stopped and waited for a minute and nothing showed up. So I got a little spooked. I started walking again and heard it again!. I knew for sure something was there with me. I was asking for it. Don't let this turn you off from visiting this fort!. This fort has history that comes to life. I'm a civilwar buff and was wearing my capi and my belt buckle. To try to show I was friendly and for spirits to come to me. This was 3pm or so too.Here are some photos too I took.
