Error Show $SQL->query

[igorlabanca]

Script:

$castle = $SQL->query("SELECT `nomeguild` FROM `gh` WHERE `nome` = 1");
<div class="panel panel-default">
                   <div class="panel-heading">
                       <h3 class="panel-title"><i class="fa fa-line-chart"></i> Guild from GH</h3>
                   </div>
                   <div class="panel-body">
                       <table class="table table-condensed table-content table-striped">
                           <tbody>
                               <?php echo $castle; ?>
                           </tbody>
                       </table>
                   </div>
               </div>

I can not show the nomeguild table, it shows this Recoverable fatal error: Object of class PDOStatement could not be converted to string in.

$castle['nomeguild'];

Do you know anything about this?
Uncaught Error: Call to a member function fetch() on boolean in C:\xampp\htdocs\layouts\metro\layout.php:10 Stack trace:

$getid = $SQL->query('SELECT `id` FROM `gh` WHERE `nome` = '.$castle['nomeguild'])->fetch();
