Changing the Location of Your Craft Templates
Problem
You want to store your Craft templates somewhere other than the default /craft/templates directory.
Solution
By default, Craft will look for your templates in the /craft/templates directory.
To override this location, set the CRAFT_TEMPLATES_PATH constant in the index.php file in the web root of your project (/public/index.php, unless you’ve renamed the “public” folder).
For example:
<?php
$craftPath = '../craft'; // This should come first.
define('CRAFT_TEMPLATES_PATH', '/mytemplates');
// The rest of the file...Discussion
