Carrauntoohill (IPA [ˌkærənˈtuːl]; Irish: Corrán Tuathail), also spelt Carrantuohill and in various other ways, is a mountain located in County Kerry, Ireland, and is the highest peak in Ireland. It is 1,039 m (3,409 feet) tall and is the central peak of the Macgillycuddy's Reeks range. There are two other peaks in this range above 1,000 m (Beenkeragh, 1,010 m; and Caher, 1,001 m) and four others on the island over 3,000 feet, in the Dingle Peninsula (Mount Brandon), south Tipperary (Galteemore) and County Wicklow (Lugnaquillia). A large metal cross 5 metres (16 ft) tall tops the peak.

The name "Carrauntoohill" derives from the Irish language Corrán Tuathail, meaning "Tuathal's sickle" .

The mountain is most often climbed from the north-east, along the Hag's Glen to the col between Carrauntoohill and Cnoc na Péiste, and then north-west up the steep Devil's Ladder. The route has become more dangerous in recent years due to loose stones and crowding . No special equipment is needed to climb the mountain, but caution is advised. Alternatively, one can walk the two other 1,000 m peaks in a horseshoe trip, starting from the west. The traverse from highest point to the second highest involves a light scramble. The weather conditions on the mountain are very changeable, and due to a high number of underdressed tourists attempting the peak each summer, there have been a number of deaths.

Carrowmore (Irish: Ceathrú Mór, meaning Great Quarter) is the site of a prehistoric ritual landscape on the Knocknarea or Cúil Irra Peninsula in County Sligo in the Republic of Ireland.

Around 30 megalithic tombs can be seen in Carrowmore today, and the traces of more (ruined) tombs have been detected. The tombs (in their original state) were almost universally 'dolmen circles'; small dolmens with boulder circles of 12 to 15 meters around them. The tombs are distributed in a roughly oval shape surrounding the largest monument, a cairn called Listoghil. The dolmen 'entrances' - crude double rows of standing stones - usually face the area of the central tomb.

Radiocarbon dates from the long-running survey and excavation project run by Stockholm University has caused controversy amongst archaeologists, particularly dates which put the earliest tombs at 5,400 BC, placing them before the (perceived) advent of agriculture in Ireland. Objections included 'old wood' theories, and simply inadequate numbers of dates. The idea of Mesolithic tomb builders is still advocated by Professor Göran Bürenhult, who excavated Carrowmore, although this runs in the face of the prevailing view, which generally associates Neolithic farming societies with megalithic sites. Supporters of the early dates sometimes point to similarly ancient dates attributed to chamber tombs in Brittany where Mesolithic microliths have been found in association with at least one passage grave, and some other very early dates in the Sligo area.

Blarney Castle is a medieval stronghold in Blarney, near Cork, Ireland. It is near the River Martin.

The castle originally dates from before AD 1200. It was destroyed in 1446, but subsequently rebuilt by Dermot McCarthy, the King of Munster. It is currently a partial ruin with some accessible rooms and the battlements. At the top of the castle lies the Stone of Eloquence, also called the Blarney Stone. Tourists visiting Blarney Castle may be positioned upside-down and kiss the stone, which is said to give the gift of eloquence. Photographs are taken of the "magic moment". There are many legends as to the origin of the stone, but some say that was the "Lia Fail" or the magical stone Irish kings were crowned upon.

Surrounding the castle are beautiful and quite extensive gardens. There are paths touring the grounds with signs pointing out the various attractions such as several natural rock formations which have been given fanciful names, a Druid's Circle, a Witch's Cave and the Wishing Steps. A newer mansion in the park, Blarney House which was built in Scottish baronial style in 1874, is also open to the public.

The Sultan Ahmed Mosque (Turkish: Sultanahmet Camii) is a mosque in Istanbul, the largest city in Turkey and the capital of the Ottoman Empire (from 1453 to 1923). The mosque is famously known as the Blue Mosque for the blue tiles adorning the walls of its interior.

The mosque was built between 1609 and 1616 by order of the Sultan Ahmed I, after whom it is named. He is buried in the mosque's precincts. It is located in the oldest part of Istanbul, in what was before 1453 the centre of Constantinople, the capital of the Byzantine Empire. It is next to the site of the ancient Hippodrome, and a short distance from what used to be the Christian Church of the Holy Wisdom (Hagia Sophia) which has now been converted into a museum.

It is within walking distance of the Topkapı Palace, residence of the Ottoman Sultans until 1853 and only a short distance from the shore of the Bosporus. Seen from the sea, its domes and minarets dominate the skyline of the old part of the city, as was its builders' intention.

Ávila de los Caballeros (Latin: Abila and Óbila) is a town in the south of Old Castile, the capital of the province of the same name, now part of the autonomous community of Castile and León, Spain.

The city is 1,117 meters above sea level, the highest capital in Spain. It is built on the flat summit of a rocky hill, which rises abruptly in the midst of a veritable wilderness; a brown, arid, treeless table-land, strewn with immense grey boulders, and shut in by lofty mountains. This means an extreme climate, with very hard and long winters, and short summers.

The ancient city walls of Avila, constructed of brown granite, and surmounted by a breastwork, with eighty-eight towers and nine gateways, are still in excellent repair; but a large part of the city lies beyond their circuit. Avila is the seat of a bishop, and contains several ecclesiastical buildings of high interest. The Gothic cathedral, said by tradition to date from 1107, but probably of 13th or 14th century workmanship, has the appearance of a fortress, with embattled walls and two solid towers. It contains many interesting sculptures and paintings, besides one especially fine silver pyx, the work of Juan de Arphe, dating from 1571.
