If you love gardens, consider having your wedding IN a garden! If you have a family member with a decent sized property and a beautiful garden, you could potentially use their space as your garden wedding venue. You could also look into local botanical gardens and conservatories. If that is not an option, you could also incorporate plants and decorations that channel the garden theme.
Aquariums or Zoos

If you like sea creatures or animals, consider an aquarium or a zoo for your wedding venue. Your wedding photos will most definitely be unique! The second picture with the penguin is from a wedding at the mansion house at the Maryland Zoo in Baltimore! Definitely a cool and unique wedding!
