What site template did that SharePoint site start as?

Sometimes you need to figure out what template was used when creating a SharePoint site,  you can mess about in the database (not recommended) you can look in the HTML of an output page as long as your master page has not changed some of the default options or you can open up the SharePoint management shell and use the following.

$web = Get-SPWeb -Identity "http://SharePointSiteURL"
$Template = $web.WebTemplate
$Template = $Template + "#"
$SiteTemplate = $Template + $web.WebTemplateID
 
Write-Host $SiteTemplate
