It can be disappointing to those who don't know it's off limits, but there's a very good reason for it.
Contrary to popular belief, the torch isn't closed off because of structural damage caused by years of wear and tear — it's thanks to an act of sabotage by Germany during World War I, according to the National Park Service (NPS).
On July 30, 1916, German saboteurs destroyed a huge cache of explosives being stored for shipment to Allied forces in World War I at Black Tom Island, a piece of land lying off of Jersey City near Liberty Island (it has since been connected to the mainland with landfill). Shrapnel from the blast, which was felt as far away as Maryland, penetrated the Statue of Liberty’s skirt and torch. Repairs weren’t completed until the next decade. The arm and torch of the statue have been closed to visitors since that incident.
While the gleaming gold of the Statue of Liberty's torch is a wonder to behold, no one can get inside and see what can only be breathtaking views of the city.

During the day and at dusk, the gold-leaf coating on the new torch reflects the sun’s rays; after dark, 16 floodlights light up in the torch, light it up.
The old torch now sits in the as-yet-unfinished Statue of Liberty Museum, which is scheduled to open in May 2019. The museum will be accessible to all visitors to the island, meaning that a wider audience will have an opportunity to appreciate the torch’s majesty.
