Belfast - the Tropical Ravine

The Tropical Ravine contains some of the oldest seed plants around today, as well as banana, cinnamon, bromeliad and orchid plants. It was built in 1889 by the park's head gardener, Charles McKimm, and his staff (Belfast City website). A balcony leads around the building. In the middle of the building - a floor beneath the level of the balcony, there is a bit of a jungle going on. It's an interesting mix of a red-brick building with a greenhouse-glass ceiling and metal structures across.

In case you can't read this: at one end of the building there is a pond with fish and the above sign: 'To ensure the continued Health and Welfare of our Fish, Please Do Not Place Unwanted Aquatic Pets in our Ponds'.
Interesting use of capital letters - and an interesting message.
