Other buildings on the island include the White House hotel, "The Mermaid" pub and restaurant, and 20 self-catering cottages. The most notable cottages are Fisherman's Cottage, north of the harbour, and Manor Cottage. There is an obelisk on The Common, in the north of the island. The White House has no clocks, televisions, or phones, which is described as "part of its charm", and has a customer return rate of 70% (i.e. each year, 70% of customers have been before). Herm has no consecrated religious buildings or resident professional clergy, but visiting clergy conducts non-denominational weekly services during the summer months, and monthly services, led by local lay people, are held during the winter.
