Why People Put Their Town Hall Outside Their Base

Have you ever wondered why people put their Town Hall on the outside of their base? I get this question a lot too and the answer is quite simple.

Here's a picture of my base and you'll see that I have my Town Hall on the outside of my base:

There are two different kind of attackers in Clash of Clans:

• The ones that want loot
• The ones that want to complete achievements

Which type do you think the Town Hall on the outside attracts? If you guessed the ones that want to complete achievements, then you guessed right. They're going after the Humiliator achievement and not loot. 

Do you put your Town Hall on the outside of your base?
