I want to know the answer to the following question:
When was the Hotel du Louvre opened?
All the background I'm provided with is that "The arrival of the railroads and the Paris Exposition of 1855 brought the first flood of tourists and the first modern grand hotels; the Hôtel du Louvre (now an antiques marketplace) in 1855; the Grand Hotel (now the Intercontinental LeGrand) in 1862; and the Hôtel Continental in 1878.". Is that enough to answer the question?
Answer: yes
