Question: Gondolin is a fictional city that had possible parallels to a city whose present-day location is known as what?
Context: Gondolin is a fictional city in J. R. R. Tolkien's legendarium, inhabited by Elves.  Found and founded with divine inspiration, it is hidden by mountains and endures for centuries before being betrayed and destroyed.  It was the mightiest of the elven homes in the Hither Lands The city was famed for its walls, and had possible parallels to Troy Roberts Park Methodist Episcopal Church, whose present-day name is Roberts Park United Methodist Church, was dedicated on August 27, 1876, making it one of the oldest churches remaining in downtown Indianapolis.  Diedrich A. Bohlen, a German-born architect who immigrated to Indianapolis in the 1850s, designed this early example of Romanesque Revival architecture.  The church is considered one of Bohlen's major works.  Constructed of Indiana limestone at Delaware and Vermont Streets, it has a rectangular plan and includes a bell tower on the southwest corner.  The church is known for its interior woodwork, especially a pair of black-walnut staircases leading to galleries (balconies) surrounding the interior of three sides of its large sanctuary.  The church was added to the National Register of Historic Places on August 19, 1982. Mount Pisgah Lutheran Church, also known in its early years as the First Lutheran Church and First English Lutheran Church and more recently as The Sanctuary on Penn, is located at 701 North Pennsylvania Street in downtown Indianapolis, Indiana.  The historic church was built by the city's first Lutheran congregation, which organized in 1837, and was its third house of worship.  The former church, whose present-day name is The Sanctuary on Penn, is operated as a for-profit event venue. Fort Crawford once provided defense for Alabama settlers in East Brewton, Alabama.  While the exact location of historic Fort Crawford is unknown, locals claim it once stood on the banks of Murder Creek near the present-day location of First Baptist Church in East Brewton. Fort Frontenac was a French trading post and military fort built in 1673 at the mouth of the Cataraqui River where the St. Lawrence River leaves Lake Ontario (at what is now the western end of the La Salle Causeway), in a location traditionally known as Cataraqui.  It is the present-day location of Kingston, Ontario, Canada.  The original fort, a crude, wooden palisade structure, was called Fort Cataraqui but was later named for Louis de Buade de Frontenac, Governor of New France who was responsible for building the fort. Camp Dunlap was a U.S. Marine Corps base activated on October 15, 1942, as a training facility during World War II.  The camp was named for Brigadier General Robert H. Dunlap.  It was used to train artillery and anti-aircraft units of the Fleet Marine Force.  The base was located at the present-day location of Slab City (also known as The Slabs) in Imperial County, California.  In October 1961, the United States Department of Defense conveyed the land on which Camp Dunlap was situated back to the State of California. 38–39 Bayley Lane is a former building, whose present-day site is accessible from the Herbert Art Gallery and Museum in Coventry, England.  All that remains is the medieval undercroft, a fourteenth-century cellar that initially belonged to a wealthy merchant, who was a clothier.  The undercroft is built with sandstone with a stone-ribbed vault for added security and strength. The Book of Revelation describes a war in heaven between angels led by the Archangel Michael against those led by "the dragon"—identified as "the devil and Satan"—who are defeated and thrown down to the earth.  Revelation's war in heaven is related to the idea of fallen angels, and possible parallels have been proposed in the Hebrew Bible and the Dead Sea Scrolls. Wampmissick or Wampmissic was a station on the Main Line of the Long Island Rail Road.  Wampmissick was named after the Native American name for extensive swamps two miles west of Manorville.  Wampmissick was 4 miles east of Yaphank and 2 miles west of Manor.  After James Wick, also known as James H. Weeks, became the president of the LIRR in 1847 he built a large woodhouse and turntable at Wampmissic and had trains stop at Wampmissic because he owned a large farm and woodlands here.  He had hoped to boom his property but when he ceased to be president the buildings were torn down.  The station was built in the years 1847–1848 when Wick was president.  The station is mentioned in the Annual Report of the American Institute, on the Subject of Agriculture, Volume 6, and in the Annual Report of the American Institute of the City of New York also in 1848, which describes a growth of herd grass by the train.  Near the present-day location of the station are streets, Weeks Avenue and North Weeks Avenue, that bear his name.  The station is mentioned in the American Railway Guide, and Pocket Companion, for the United States from 1851, although no trains are listed as stopping there.  It only appears on the 1852–1853 timetable.  It was also used as a meeting and passing location.  It also appears on an 1855 map, and in A New and Complete Statistical Gazetteer of the United States from 1855.  The station appears again in 1857 in Mitchell's New Traveller's Guide. Troy (Ancient Greek: Τροία , "Troia" and Ἴλιον , "Ilion", or Ἴλιος , "Ilios"; Latin: "Trōia" and "Īlium" ; Hittite: "Wilusha" or "Truwisha"; Turkish: "Truva or Troya" ) was a city situated in the far northwest of the region known in late Classical antiquity as Asia Minor, now known as Anatolia in modern Turkey, near (just south of) the southwest mouth of the Dardanelles strait and northwest of Mount Ida.  The present-day location is known as Hisarlik.  It was the setting of the Trojan War described in the Greek Epic Cycle, in particular in the "Iliad", one of the two epic poems attributed to Homer.  Metrical evidence from the "Iliad" and the "Odyssey" suggests that the name Ἴλιον ("Ilion") formerly began with a digamma: Ϝίλιον ("Wilion"); this is also supported by the Hittite name for what is thought to be the same city, Wilusa.
Answer: Hisarlik
