Rosenborg and Kongens Have: castle in the garden
Christian IV's Renaissance castle in the middle of Copenhagen's oldest park, with the crown jewels in the basement. This is a Claude-drafted route awaiting the editor's walk.

1. Nørreport
Copenhagen's busiest transit knot — M1, M2, M3 Cityringen, plus the regional S-tog. The park's main gate is two minutes east on *Gothersgade*; you'll cross the bike traffic before you see the trees.

2. Kongens Have main entrance
The Gothersgade gate into Copenhagen's oldest royal garden, laid out under Christian IV in the early 1600s. The lime trees were planted in the 1660s and have been replanted since, but the avenues are the king's. Locals lie on the lawn from May to September.

3. Rosenborg Slot
Christian IV's 1606 Renaissance summer castle, expanded twice during his reign and never properly left. Pay to go inside — the audience halls upstairs (the Knights' Hall with its silver lions, the Long Hall with the tapestries) are the architectural payoff; the *Skatkammeret* basement is where the Danish crown jewels and the Coronation Throne live. Closed Tuesdays in winter.

4. Hercules Pavilion (Herkulespavillonen)
A small 1773 garden folly in the southern grounds, named for the marble Hercules statue inside. The Renaissance garden originally extended much further south; this pavilion marks where it once ended. Easy to miss between the lime alleys.

5. Botanisk Have + the Palm House
Across *Øster Voldgade* on the old rampart land. The University of Copenhagen's Botanical Garden, free entry to the grounds. The *Palmehus* (1874) is a smaller, gentler cousin to Kew's Palm House — iron and glass on a domestic scale, open every day. The pond around it is part of the old city moat.

6. Back to Nørreport
The botanical garden's southern exit lands you at *Nørreport*. M3 Cityringen orbits the centre, M1/M2 head north or south, S-tog runs to anywhere in greater Copenhagen.
