Query: What is the oldest active lighthouse in the world?
The Hook Lighthouse (; also known as Hook Head Lighthouse) is a building situated on  Hook Head at the tip of the Hook Peninsula in County Wexford, in Ireland. It is one of the oldest lighthouses in the world and the second oldest operating lighthouse in the world, after the Tower of Hercules in Spain. It is operated by the Commissioners of Irish Lights, the Irish Lighthouse Authority, it marks the eastern entrance to Waterford Harbour. The current structure has stood for 846 years as of 2018.

Mauna Kea ( or , ) is a dormant volcano on the island of Hawaii. Its peak is above sea level, making it the highest point in the state of Hawaii. Most of the mountain is under water, and when measured from its oceanic base, Mauna Kea is the tallest mountain in the world measuring over . Mauna Kea is about a million years old, and has thus passed the most active shield stage of life hundreds of thousands of years ago. In its current post-shield state, its lava is more viscous, resulting in a steeper profile. Late volcanism has also given it a much rougher appearance than its neighboring volcanoes due to construction of cinder cones, decentralization of its rift zones, glaciation on its peak, and weathering by the prevailing trade winds. Mauna Kea last erupted 6,000 to 4,000 years ago and is now considered dormant. The peak is only about higher than its more massive neighbor, Mauna Loa.
The Brick Gothic church in Suurhusen is reminiscent of the old fortress churches. Originally, it was 32 metres long and 9.35 metres wide. In 1450 the church was shortened by about a quarter and the tower was built in the space. This tower currently leans at an angle of 5.19°, compared with 3.97° for the Pisa tower after its stabilization.
In 2006, the Guinness Book of World Records certified Katlinel and Les Hartness of California as having the largest hand-carved wooden rocking horse on record. This rocking horse was built in 2000 and is 7 feet 8 inches tall and weighs 1,200 pounds. It can be seen at renaissance faires, faerie festivals, and at private parties and events where up to 3 adults or 4-5 children can ride it together at one time. According to Les and Katlinel, the youngest rider has been six weeks old and the oldest, 94 years.
The Peace Candle was first erected in 1951, and has been put up almost every year since then. Due to damage or disrepair, the Peace Candle has been replaced with new candle structures twice since the original construction. The first candle lasted until 1968, the second candle from 1969 to 1989, and the current candle was built in 1990 and is expected to last until around 2014. The structure is dedicated to the Easton area men and women who have served or are serving in the United States armed forces.
The oldest structure, Temple I, is exposed on the west side of the structure, at the pyramid’s base. This section dates from approximately the 6th century AD, deduced from a date inscribed on the door lintel and radiocarbon dating. The façade of this structure is heavily decorated with masks of the rain god, Chaac, a characteristic of the Chenes style of architecture, though the masks may have been added at a later date. The rest of the structure is covered by subsequent construction. The passageway that led to this structure was closed off after the drenching rains of Hurricane Gilbert in 1988 in order to assure the preservation of the building.

The state has numerous large islands, the principal ones being the Manitou, Beaver, and Fox groups in Lake Michigan; Isle Royale and Grande Isle in Lake Superior; Drummond, Marquette, Bois Blanc, and Mackinac islands in Lake Huron; and Neebish and Sugar islands in St. Mary's River. Michigan has about 150 lighthouses, the most of any U.S. state. The first lighthouses in Michigan were built between 1818 and 1822. They were built to project light at night and to serve as a landmark during the day to safely guide the passenger ships and freighters traveling the Great Lakes. See Lighthouses in the United States.
The Old or Grand Bazaar "(Çarshia e Madhe)" in Gjakova is the oldest bazaar in Kosovo, and it served as an Ottoman trading centre and heart of the town economy. It suffered damage during the Kosovo War but has since been renovated. The Hadum Mosque, built in the 16th century, lies by the bazaar, and includes a highly decorated graveyard, where the town notables were buried. Within the mosque complex were the "hamam" which was destroyed in 2008, the "Old library" from 1671, damaged in the Kosovo War, and also a "meytepi" from 1777. The Bazaar is linked to the city centre, just five minutes away via the Islam-Beg Bridge.

Banca Monte dei Paschi di Siena was founded in its present form in 1624, but traces its history to a mount of piety founded in 1472. The Berenberg company was founded in 1590 and has operated continuously ever since with the same family as owners or major co-owners. Banca Monte dei Paschi di Siena is today a large Italian retail bank, while Berenberg Bank is primarily involved in investment banking and private banking for wealthy customers; in any event Berenberg Bank is the world's oldest merchant bank or investment bank.

Bedum's 36-metre tower of the St Walfridus church has been calculated as now leaning at a greater angle than the leaning tower of Pisa. If both towers were the same height, Bedum's would have a greater displacement by 6 cm.
A memorial to FitzRoy is erected atop a metamorphic outcrop beside the Bahia Wulaia dome middens on Isla Navarino, in the Chilean part of Tierra del Fuego archipelago, South America. It was presented in his bicentenary (2005) and commemorates his 23 January 1833 landing on Wulaia Cove. Another memorial, presented also in FitzRoy's bicentenary, commemorates his Cape Horn landing on 19 April 1830.
Longships for the most part used two different kinds of anchors. The most common was a natural wood yoke formed from a tree branch. The weight was supplied by a stone passing laterally through the U of the yoke. The top of the yoke was closed by either a length of hardwood or a curved iron head, which kept the stone in place. One side of the head stuck out so it could dig into mud or sand. In the Ladby ship burial in Denmark, a unique iron anchor has been found, resembling the modern fisherman's anchor but without the crossbar. The cross bar may have rusted away. This anchor—made of Norwegian iron—has a long iron chain to which the hemp warp was attached. This construction has several advantages when anchored in deep waters or in rough seas.
North of this area, on the slope of Mt Haszard, is Inferno Crater, filled with a striking pale blue lake of highly acidic water with a pH as low as 2.2. The crater was blasted into the side of the mountain as part of the 1886 Mount Tarawera eruption event and remains the site of the largest geyser-like feature in the world. Although the actual geyser plays at the bottom of the lake and cannot be seen, a handful of active fumaroles are visible on the shore and the cliff face behind the lake. The water level of this up-to- lake follows a complicated rhythmic cycle that is interconnected with the nearby Frying Pan Lake.
Admiralty House is located in Mount Pearl, Newfoundland. It was proposed in 1914 for the British Admiralty as a World War I communications post. It was constructed in 1915 by the Macroni Telegraph Company to serve the British Navy. This station, is now the last standing of 11 identical stations around the world. It was built to intercept secret German naval transmissions, track icebergs and track ships in distress. Today, it houses a museum, with exhibits on the history of Mount Pearl, Guglielmo Marconi and wireless communications, the wreck of SS "Florizel", and HMS "Calypso" (later HMS "Briton"), a training ship for the Newfoundland Royal Naval Reserve before and during World War I. The museum also house several collections and fonds detailing life in early 20th Century Canada. These include photos and documents from both World Wars.
To the southeast of the park is Oslo’s oldest building – Aker Kirke, built around 1100, but restored from ruins around 1860, and then again in the 1950s in a more authentic style. Next to the church is the cemetery Vår Frelsers gravlund, created in 1808 as a result of the great famine and cholera epidemic of the Napoleonic Wars. The nearby area around Damstredet and Telthusbakken is interesting since it retains the small town character of Oslo in the first part of the 19th century.

During the summer months when there is a U.S. National Park Ranger on duty, visitors may access the base of the lighthouse. Access to the top of the lighthouse is not allowed due to the simple steel spiral staircase being safe only for maintenance activity.
Boston Light is a lighthouse located on Little Brewster Island in outer Boston Harbor, Massachusetts.
