Hugh Street is the main shopping area on the islands and business is quite reliant on tourism. There are several pubs, restaurants and hotels, as well as two banks and a post office. A notable building is the Star Castle, which overlooks the town from The Garrison and is now a hotel. Similarly, Tregarthen's Hotel is a Hugh Town landmark. It was originally the home of Captain Tregarthen who introduced the first sloop in 1849, 'Ariadne', that serviced the Hugh Town from Penzance. Being on an isthmus, there are two beaches, the northern one (Town Beach) being along the bay which forms the island's main harbour; the southern beach and bay is named Porthcressa.
