are the preferred means of local sea transport, being particularly suitable for navigation among floating ice and landing at places lacking port facilities. Naturally, this is only possible in summer as the sea surface is partially or completely frozen in ice over one meter thick in winter. Visits by yachts and extreme tourism such as kayaking have become increasingly popular, too. Cruise ships visiting Hannah Point occasionally make a sightseeing detour to the Bulgarian base, where the tourists could visit the Livingston Island Museum established in October 2012, the old and new chapels of St. Ivan Rilski – the first Eastern Orthodox edifice in Antarctica consecrated in February 2003, and the Monument to the Cyrillic Script erected on Pesyakov Hill in March 2018. Livingston Island has some particular relationship with the Cyrillic alphabet as the modern system for the Romanization of Bulgarian was developed in 1995 for use in Bulgarian-related place names on the island by the Antarctic Place-names Commission, and later became official for Bulgaria, UK, USA and UN. The northeasternmost slopes of Tangra Mountains between Elena Peak and Renier Point together with the adjacent portion of Sopot Ice Piedmont are a popular site for backcountry skiing and climbing, with skiers landed by Zodiac boats from cruise ships visiting Half Moon Island's vicinity. Honours Several squares and streets in Bulgarian towns and cities are named after Livingston Island, such as Livingston Island Square in Samuil and Kula, and Livingston Island Street in Gotse Delchev, Yambol, Petrich, Sofia, Lovech and Vidin.
