The London Transport Museum, housed in the former flower-market building in Covent Garden, offers a fascinating glimpse into the city's development through its improved transportation. Inside, visitors can explore horse-drawn omnibuses, vintage Underground carriages with historic maps, and climb aboard some classic double-decker buses. It's an exciting playground for kids and adults alike. After exploring, visitors can pick up a few London souvenirs from the museum's gift shop, including retro Tube posters and pillows made from train seat fabric.
