I guess not many people in Singapore knows the existence of this place. It's the Wallace Education Centre at the Dairy Farm Nature Park.
Can you imagine that Singapore had a cowshed long ago?
You can read more about about this Nature Park at the National Parks website.
Oh, I found a website that has all things Alfred Russell Wallace if you are interested to read more about him. http://wallacefund.info
Look at the Moo above, do you like dairy products? My favourite dairy based food is not milk or cheese. It's ice cream!
