Fort Lytton National Park is one of the smallest national parks I have ever been to and is just dedicated to the 1881 defensive fort near the mouth of the Brisbane River. It is only open to the public on Sundays. The grass was pretty lush and long as we had a fair bit of rain and humidity, which really makes everything grow faster. You can just make out a cement factory in the background on the north side of the river. The guns pictured are a 64 pound rifled muzzle, loading gun that is capable of firing a 29kg projectile up to 4 kilometres.
