Location and visiting.
The statue is situated in Upper New York Bay on Liberty Island, south of Ellis Island.
Both islands were ceded by New York to the federal government in 1800.
As agreed in an 1834 compact between New York and New Jersey that set the state border at the bay's midpoint, the original islands remain New York territory despite their location on the New Jersey side of the state line.
Land created by reclamation at Ellis is New Jersey territory.
No charge is made for entrance to Statue of Liberty National Monument, but there is a cost for the ferry service that all visitors must use, as private boats may not dock at the island.
A concession was granted in 2007 to Statue Cruises to operate the transportation and ticketing facilities, replacing Circle Line, which had operated the service since 1953.
The ferries, which depart from Liberty State Park in Jersey City and Battery Park in Lower Manhattan, also stop at Ellis Island when it is open to the public, making a combined trip possible.
All ferry riders are subject to security screening, similar to airport procedures, prior to boarding.
Visitors intending to enter the statue's base and pedestal must obtain a complimentary museum/pedestal ticket along with their ferry ticket.
Those wishing to climb the staircase within the statue to the crown purchase a special ticket, which may be reserved up to a year in advance.
A total of 240 people per day are permitted to ascend: ten per group, three groups per hour.
Climbers may bring only medication and cameras—lockers are provided for other items—and must undergo a second security screening.
The Hermann Heights Monument is a statue erected in New Ulm, Minnesota.
The statue depicts Hermann the Cheruscan, also known by the Latin name Arminius, but locals refer to the statue as Hermann the German.
The only National Register of Historic Places property of its kind in Minnesota, the monument remains an impressive remembrance of German ancestry for many Minnesotans.
Visitors to the statue can climb the spiral staircase to an observation platform at the base of the statue, which commands a view of the town and the Minnesota River Valley below. 
The jig is used to make finish stringers, in interior staircase fabrication.
The stringer is also referred to as a skirtboard.
It can be used in a closed staircase or an open staircase where one side of the staircase is exposed and the other is housed into the skirtboard. 
Visiting the grotto involves a steep climb over uneven ground so access can be difficult. 
A 40-meter statue of José María Morelos, a great hero of Mexico's independence, started in 1933, is found on the island's highest point.
Visitors can climb to the top of the statue by way of a staircase that spirals up the inside.
Along the interior walls, the life of Morelos is depicted in murals painted by Ramón Alba de la Canal and other great Mexican muralists.
Although the steep stairway can become congested and distract one's attention, it is a good Mexican history lesson.
At the top, one can peer through peepholes in the giant raised fist of Morelos, giving a spectacular view of the island, lake and surroundings.
