Antique roof tile predicament

And further to my last post, here's a quick question for you all. Below is a roof tile that comes from the house that Kaoru's mother grew up in, which was in Hita City. It's estimated to be between 100-150 years old. Originally my plan was to add it to our house, and so now, as the exterior is being done, my thoughts are turning to it. Here's a pic, so you can see what I mean...

My question is, should this go in the gable above the four windows at the front of the house, or should it perhaps find a place inside the house? It's quite heavy - I estimate it weighs at least 5kgs. Thoughts anyone??
