The Orthodox Church of Our Lady of the Sign in Vilnius is a beautiful and historically significant religious site. Accessibility information is limited, so it's best to check in advance for wheelchair access. A solo visit is easily manageable, allowing for personal reflection, though a guided tour could offer deeper insights into its history and art. There are generally no seasonal restrictions, but check the church's schedule for services or events that might affect visiting hours. Entry is typically free, but donations are welcome; budget a small amount for candles or souvenirs. A typical visit lasts about 30-60 minutes, depending on your level of interest. Dress respectfully when visiting.
