Adding a custom taxonomy name as a title on its archive page

Hi,
I have a custom post type and custom taxonomy set up.
I wish to add the name of the relevant custom taxonomy as an H1 heading on its archive page.
I added archive.php to my child theme and inserted the following line:
<h1 class="custom-cat-title">You are now in <?php foreach((get_the_category()) as $category) { echo $category->cat_name . ' '; } ?> category.</h1>
This works fine for normal post category archive pages but does not work with my custom taxonomies (I guess that get_the_category is only for categories which custom taxonomies are not).
Could you please provide me a snippet that will achieve this? I havbe been trying using get_the_terms without much luck.
Many Thanks, M
