In my area we still have communities that drive horse and buggy. The arrangements for parking your horse haven't changed significantly in the last 120 years.
Any place where people are likely to park their horse there is a hitching post, a simple horizontal bar on top of vertical posts that you can tie the reins to. These days there is often shelter for the horse too. At churches there are enough hitching posts, spaced out around a "parking lot" for as many horses as are expected, but they are not covered. The hitching posts are spaced so that you can park the horses without unhitching them from the buggies.
There aren't stables. People care for their horses at home.
